Question: 1 / 400

How many warning devices should a driver set out after an accident?

Two devices

Three devices

After an accident, the correct number of warning devices a driver should set out is three. The purpose of these devices is to alert other motorists and ensure their safety as well as the safety of those involved in the accident.

Typically, the guidelines state that one warning device should be placed at the nearest point of the incident, while the other two should be spaced further back along the roadway, usually at 100 feet and 200 feet from the accident scene in either direction. This strategic placement creates a clear line of warning for approaching traffic, reducing the risk of further collisions and enhancing the safety of everyone in the vicinity. It’s essential for drivers to be aware of how to properly use warning devices, as doing so plays a crucial role in accident response protocols.
