What is the best strategy to use when following another vehicle to avoid crashes?

Answer: B — The two second rule

The best strategy to use when following another vehicle to avoid crashes is the two second rule. This rule advises a driver to maintain a minimum of a two-second following distance behind the vehicle in front of them. By using this rule, drivers can ensure they have enough time and space to react to any sudden stops or changes in traffic conditions. Option A, the three second rule, is not as precise as the two second rule and may lead to following too closely. Option C, the one second rule, does not provide enough time to react in case the vehicle in front suddenly stops. Option D, the five second rule, while safer than following too closely, may be excessive in normal driving conditions and could result in unnecessary delays for other drivers.
