safe-driving
What following gap is suggested for an expressway in bad weather?
- At least four seconds behind the vehicle ahead
- One second, because expressways have wide lanes
- Two car lengths regardless of speed or weather
- No gap if the driver is traveling below the maximum limit
Answer: At least four seconds behind the vehicle ahead. Expressway guidance calls for three seconds behind the vehicle ahead in ordinary conditions and four seconds in bad weather. The extra second accounts for reduced traction, spray, and longer braking distance. Wide lanes do not make a one-second gap safe, and a fixed two-car-length measure changes with speed and can be far too short. Staying below the maximum limit does not remove the need for space. Use a visible roadside object to time the gap, then lengthen it whenever rain, snow, or other conditions reduce control.
