What should you do if you are involved in a crash?

Answer: B — Wait until authorities arrive to investigate

You should wait until authorities arrive to investigate because leaving the scene of the accident is illegal and could result in additional charges. Additionally, it is important to provide any necessary information to the authorities so they can properly investigate the incident and determine who was at fault. Simply trying to determine fault on your own could lead to biased or inaccurate conclusions. It is also important to exchange information with the other driver, but this should be done under the supervision of the authorities to ensure that all necessary information is shared and accurate.
