Question

Daytime running lights Canada requires that cars be equipped with “daytime running lights,”

headlights that automatically come on at a low level when the car is started. Some manufacturers are now equipping cars sold in the United States with running lights. Will running lights reduce

accidents by making cars more visible? An experiment conducted in a driving simulator suggests that the answer may be “Yes.” What concerns would you have about generalizing the results of such an experiment?

Short answer

Simulator users are also likely to be in a different mindset than they are when driving in life.

Step-by-step solution

Given information

Daytime running lights can help to decrease accidents by increasing visibility during the day. The usage of daytime running lights also aids drivers in determining the vehicle's size.

Concept

Human studies must be approved by an institutional review board in advance. Before taking part, all participants must express their informed consent. Any information regarding the study participants must be kept private.

Explanation

It is stated in the question that cars in Canada must have daytime running lights and headlights that automatically turn on at a low level when the car is started. As a result, one of our worries about extrapolating the results of such an experiment is that a driving simulator is unlikely to accurately represent all driving circumstances. Simulator users are also likely to be in a different mindset than they are when driving in real life.
