Safe Driving第 35 / 120 题
You are approaching a curve posted at 40 mph while driving a loaded tractor-trailer. What is the safest approach?
a.Enter at 40 mph and brake through the curve
b.Enter at 45 mph and coast
c.Brake in the middle of the curve to control speed
d.Slow to about 10 mph below the posted speed before entering, then accelerate gently through the curve
解析
Posted curve speeds are set for passenger cars, so a high, heavy vehicle should be well below them and should complete braking before the curve begins. Braking inside a curve can break traction and cause a skid or rollover, and coasting through above the posted speed invites a rollover.
