Driving SafelyPregunta 52 de 60
At 50 mph in a 60-foot combination vehicle, about how many seconds of following distance should you keep?
a.1 second
b.2 seconds
c.3 seconds
d.At least 7 seconds (6 for length plus 1 for speed over 40 mph)
Explicación
Using the rule of 1 second per 10 feet of length, a 60-foot vehicle needs 6 seconds, and you add 1 second for speeds over 40 mph, for a total of about 7 seconds. This extra space accounts for the vehicle's long stopping distance. In bad weather or on hills you should allow even more.
