You drive at 50 mph on a two-lane road. A yellow warning sign shows a sharp curve ahead, with a 25 mph advisory speed plate below it. When should you slow down?
A approaches a sharp left curve on a two-way road at 50 mph. Exact reviewed warning and 25 mph advisory faces identify the given signs.
Correct answer: Before the curve, so that you are near 25 mph when you start to turn
Why
Warning signs and advisory speed plates give you time to slow down before a hazard. Brake on the straight part of the road, enter the curve at the lower speed, and keep a steady speed or accelerate slightly as the road straightens. A driver who enters too fast must brake while turning, and that can cause a skid or push the car into the other lane.
