The temperature is near freezing. The road looks dry, and the posted limit is 45 mph. You approach a bridge in a shady area. What speed should you choose?
A approaches a shaded bridge over a stream on a dry-looking two-lane road. The card states that the temperature is near freezing and the posted limit is 45 mph. No ice patch is shown.
Correct answer: Below 45 mph, since black ice can form there on a dry-looking road.
Why
Rhode Island's Basic Speed Law requires you to drive only as fast as conditions allow; the posted limit is the maximum for ideal conditions. Black ice is hard to see and often forms first on bridges, off-ramps, intersections and shady areas. Slow down before you reach these places, and brake early and gently so that the tires keep their grip.
