Illinois CDL Practice Exam

How far ahead should a driver look when driving in traffic?

1. 6 to 8 seconds

2. 12 to 15 seconds

3. 20 to 25 seconds

4. 30 to 35 seconds

The correct answer is: 12 to 15 seconds

A driver should look 12 to 15 seconds ahead when driving in traffic to maintain a safe and controlled driving environment. This practice allows the driver to anticipate potential hazards, plan lane changes, and react to any shifts in the movement of other vehicles. By focusing ahead within this time frame, a driver can assess the flow of traffic, identify when to slow down or accelerate, and be prepared for any sudden stops from vehicles in front. This forward-looking strategy contributes to overall road safety and enhances situational awareness, which is crucial in navigating busy roadways effectively. In this context, other response options suggest looking too far or too close ahead, which could hinder a driver's ability to react appropriately to immediate conditions on the road. Looking beyond 15 seconds might lead to a decreased focus on the immediate surroundings, while looking shorter may not provide enough time to respond to more distant threats.
