Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane. In many nearby towns, speed humps (raised areas of pavement placed across residential streets, about 300 feet apart) have reduced traffic speeds on residential streets by 20 to 25 percent. In order to reduce traffic speed and thereby enhance safety in residential neighborhoods, Ardane's transportation commission plans to install multiple speed humps in those neighborhoods.
Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps.
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed.
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators.
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps.

A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit. - strengthens. Incorrect.
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. - irrelevant.
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. - irrelevant.
D. //Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares// ((unless warned by signs and painted indicators.)) - though first part might lead to something like it poses danger etc.; however, the second part makes it weird and kinda irrelevant. According to the second part the plan would be ok, if indicators are put. But, the argument doesn't say they won't put an indicator or vice versa. So it is a strengthener and also irrelevant.
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where //bicycles can travel //without going over// the humps.// - this casts a doubt whether the plan will succeed as the bicyclists might misuse it and chance of accidents would still exist and road safety is not guaranteed in this way.

i think the answer should be D, as it says that motorists unaware of the speed-breakers might be involved in an accident and thus not necessarily increasing the "safety" of the neighborhood

i guess you could be assuming that by making them come to a complete stop, they will turn up late. Also, this would not reduce the safety in the neighborhood, would it?

IMO it is clear B Conclusion (Ardane transport authority goal.) :- In order to reduce traffic speed and thereby enhance safety in residential neighborhoods
so if fire and ambulance have to stop amid a rescue, that halt will most likely jeopardize the safety of ardane population.
correct me if I a wrong.

Well the argument is about the neighborhoods that have these speed breakers and not the whole city in general
what are we looking for - identify a serious drawback
Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane.

Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit. It rather gives a reason for humps
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. This is a serious drawback and there is no way to overcome it. Remember we are looking for a drawback, not looking to strengthen or weaken argument
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. not a drawback
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators. Trap... Yes it is a problem but there is a solution in the choice itself .. - warn by signs and painted indicators
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps. Not a drawback. Most have small area left on sides of humpfor cycles.

here is my reasoning
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.
this option favors installation of humps, so A is out
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps.
this one is the most logical answer choice since we talk about installing humps that limit speed, it will definately be a problem for emergency vehicles just imagine an ambulance driving at a speed of 150mph, emergency pizza delivery in 10 minutes
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed.
this option gives information that speed in Ardane is higher. that means it strengths the initiative of installing humps, hence C is out
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators.
this one doesnt give reason to not install humps, there will always be motorists unaware of humps everywhere in the world moreover the main topic isnt about motorists and painted indicators, we are concerned about speed limit d humps hence D is out
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps.
this option is totally irrelevant , do we talk about Bicyclists ? no ! its about cars and speed limit hence E is out

Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit. -- No impact. It is already given in the passage.
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. -- Correct Answer. This is a major drawback of installing speed hump.
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. -- So what ?? - In a few cases vehicle will be slower than required, There is no big deal in that. (@ least when we have a better choice - b).

IMO B.
The goal of the plan is "to reduce speed and thereby to enhance safety". But according to B, if vehicles such as fire trucks and ambulances would come to a halt then this would be a problem for safety.Hence the said goal will not be achieved.

Pre-think: Just for Information , these humps are called speed-breaker in India, and they have full potential to kill someone. if a person could not see clearly, he/she is going to face trouble.
Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.--- this info is already given.
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. --- quiet a potential answer. Well this is one of the drawbacks of having a hump. this hump will slow down a safety vehicle too. Although I doubt this option is true In India.
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. ---- not a weakener.
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators. --- then paint the indicator and problem solved. very far from weaken the conclusion.
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps. --- So do this and problem solved. not a weakner again.

Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
Argument: Speed humps proved successful in nearby towns. Therefore, Arcane should install these speed humps to reduce traffic speed and thus ensure safety. What sort of an answer choice we are looking for -> We need an answer choice that is a drawback for this plan. An answer choice that shows despite the installation, either traffic speed will not be reduced or safety will not be ensured. For example, say that installation of speed humps causes people to avoid certain routes and speed on others causing more accidents etc.
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.All the more reason to install the speed humps then! This is not a drawback
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps.Ahh..so looks fire trucks and ambulances that are required in emergency situations would be impacted. If firetrucks slow down, fires would cause more damage than they would have had the trucks been quicker. Clearly, the safety of people is in question!
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. All the more reason to have speed humps then! This choice gives us no reason to believe why the installation would not slow the traffic down.
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators.Firstly, what proportion of people are unfamiliar with these streets? The argument does not tell us that. Moreover, warning signs could be a part of the installation process.
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps.Good to know fact but does not tell us anything much! Even if transport commission adheres to the preference of the bicyclists, we have no reason to believe why the other traffic will not slow down.

To reduce traffic speed & enhance safety in residential neighborhoods - install multiple speed bumps
What is the drawback? traffic speed will be low & safety is also one of the concern
Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
Question Stem is asking to find the serious draw back. Serious drawback in decreasing order can be assumed as - 1) Safety of Life. (Most Serious) 2) Safety of Accident - Degree of injury is unknown (Serious) 3) Traffic speed (Least Serious)
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit. This is drawback for not installing speed humps. We have to evaluate drawback for installing speed humps. Incorrect
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. Most Serious Draw Back.
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. Serious Draw Back.
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators. Safety of Accident - Serious Draw Back
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps. Safety of Accident - serious Draw Back.
Now measure each option in terms of seriousness.
B is the most serious draw back. IMO - B _________________

NEW question from GMAT® Official Guide 2019
(CR04925)
IMO B
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit. This is a Strengthener.
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. Correct Answer as this talks about the drawback of installing too many speed humps and addresses safety issues.
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. Irrelevant // Out of scope. This compares the speed limits with nearby towns.
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators. Irrelevant // Out of scope. Talks about signs and indicators of speed humps. Plain weird.
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps. Irrelevant // Out of scope. Talks about bicyclists instead of Motor vehicles. Bicyclists aren't a concern when addressing road safety issues. _________________

Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane. In many nearby towns, speed humps (raised areas of pavement placed across residential streets, about 300 feet apart) have reduced traffic speeds on residential streets by 20 to 25 percent. In order to reduce traffic speed and thereby enhance safety in residential neighborhoods, Ardane’s transportation commission plans to install multiple speed humps in those neighborhoods.
Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit. B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps. C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed. D. Motorists who are not familiar with the streets in Ardane’s residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators. E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps.
Question Type: Weaken BID (Boil It Down): Bumps reduce speed, so we should have bumps to enhance safety. Missing Information (Assumption): Installing the speed humps will not have serious negative consequences. Goal: Undercut the notion that the new humps will generate an improvement in safety/point out a significant downside of the humps.
Choice B is correct. Though traffic might be slowed considerably, slowing emergency vehicle down to a stop is obviously a negative consequence if the objective of the plan is to ENHANCE SAFETY. This option certainly doesn’t crush the plan, but it does raise a substantial drawback to the plan’s goal of enhancing safety. Reducing emergency response time could be a pretty big freaking problem for safety.
Choice A does not tell us anything new about the lack of wisdom of installing the humps. We already know there Ardane has a speeding problem.
Choice C makes an irrelevant comparison. Even if the speed limit in Ardane were higher than in neighboring towns, installing the humps could and would likely reduce speeding (maybe improving safety even more dramatically). This option certainly doesn’t detract from the wisdom of installing humps.
Choice D would only be a drawback if there were no signs, but of course there could be. We don’t know that Ardane is even contemplating not installing signs, so this option doesn’t have any clear negative force on the plan.
Choice E has absolutely zero impact on the plan. Having spaces on either side on the humps for bicycles may or may not be done, and whether it is or isn’t has no clear impact on the safety outcome of the plan. Dump it.
