What is the safest approach when driving in heavy traffic?

Maintaining a two-second interval behind the vehicle ahead is the safest approach when driving in heavy traffic. This following distance provides adequate time and space to react to sudden stops or emergencies, which are common in congested conditions. It allows the driver to observe the movements of the vehicle in front and to anticipate any necessary adjustments in speed.

A two-second gap helps reduce the risk of rear-end collisions, which are frequently caused by miscalculating stopping distances in heavy traffic. By keeping this safe distance, drivers can better manage their response time, adapt to changing traffic dynamics, and, if necessary, brake safely without needing to swerve or make abrupt maneuvers.

In contrast, driving closely to the vehicle ahead creates risks, as it can lead to tailgating, which tends to increase the likelihood of accidents due to reduced reaction time and pressure on the driver to maintain speed.
