What is your daytime reaction time while driving?

• A. 1.0 seconds.
• B. 1.4 seconds.
• C. 1.6 seconds.
• D. 2.0 seconds.

Answer: (C)

Reaction time in driving is the interval from when you notice a hazard to when you start to act (brake or steer). For daytime driving, the typical figure teachers and safety programs use is about 1.5 seconds, with 1.6 seconds often cited as a standard average. This makes 1.6 seconds the best choice because it represents a realistic, commonly taught expectation for an alert driver during the day.

Think of it this way: longer reaction time means more distance traveled before you begin to slow or steer, which increases overall stopping distance. The other options are either faster than what most drivers can consistently achieve (1.0 seconds), slightly below the standard daytime expectation (1.4 seconds), or much slower (2.0 seconds), which would suggest fatigue or distraction.
