When driving, consider how often you look down to check your speed. Even with a good sense of your current velocity, entering a known enforcement zone or seeing a posted limit forces you to stop what we are doing and take quick peeks at the speedometer. It may only be a fraction of a second each time, but that’s still a fraction of a second where you aren’t paying full attention to the road ahead.
You might think that the average motorist is perfectly capable of such basic multitasking without causing additional risk. According to new research, you might be wrong.
