Source pages 41, 42 Wyoming sets default speed limits that apply unless a sign says otherwise. But the legal limit is only the maximum. You must slow down for curves, blind corners, slick roads, darkness and poor visibility.
Know the rule
Your car touches the road only through its tires, each with a patch of rubber about the size of a hand, so drive according to road conditions.
Handbook p. 41 ↗ Know the rule
Adjust your speed BEFORE entering a curve. Going too fast can break the tires' grip on the road.
Handbook p. 41 ↗ 15 mph Top speed approaching a "blind" intersection where trees, bushes or buildings block your view
Handbook p. 41 ↗ Match the flow of traffic: Going faster than traffic means passing many vehicles, which raises your crash risk Going slower or stopping suddenly is as dangerous as speeding (rear-end and passing risks) Spot slower vehicles early and adjust gradually; slowing suddenly is a major cause of crashes Treat bicycles as slow-moving traffic; bicyclists have as much right to the road as you Handbook p. 41 ↗ Know the rule
Never drive faster than you can stop within your headlights. Above 55 mph on a dark road you're "driving blind."
Handbook p. 42 ↗ 100 feet If heavy rain, snow or fog keeps you from seeing farther, you can't drive safely at any speed
Handbook p. 42 ↗ Know the rule
Whenever you can't see well enough, pull off the road and wait until it clears.
Handbook p. 42 ↗ Put it into practice
It's raining on a rural highway posted 65 mph. The road is wet, so reduce your speed by at least 5-10 mph. If the rain gets so heavy you can't see 100 feet ahead, pull off and wait.
A useful reminder School 20, town 30, secondary highway 70, interstate 75 or 80.
Check your understanding Read the question, decide on an answer, then open it to check the explanation. These are Roadwise study questions based on the source handbook.
What is Wyoming's legal speed limit on secondary highways, unless otherwise posted? 70 mph 60 mph 65 mph 75 mph Answer: 70 mph
Wyoming's legal speed limit for secondary highways, unless otherwise posted, is 70 mph.
Handbook p. 41 ↗ What is the unposted legal speed limit in a Wyoming school zone? 15 mph 20 mph 25 mph 30 mph Answer: 20 mph
The legal speed limit in school zones, unless otherwise posted, is 20 mph.
Handbook p. 41 ↗ Approaching a blind intersection where buildings block your view, what speed should you use? No more than 15 mph No more than 25 mph No more than 10 mph No more than 20 mph Answer: No more than 15 mph
Approach a blind intersection at no more than 15 mph because trees, bushes or buildings can block your view.
Handbook p. 41 ↗ On a wet road, how much should you reduce your speed compared to a dry road? At least 20-25 mph At least 5-10 mph At least 1-2 mph By at least half Answer: At least 5-10 mph
On a wet road, reduce speed by at least 5-10 mph.
Handbook p. 41 ↗ On a dark road, why are you really 'driving blind' if you drive faster than 55 mph? You can't stop within the 250 feet your headlights light You can't stop within the 500 feet your headlights light You can't stop within the 100 feet your headlights light You can't stop within the 1,000 feet your headlights light Answer: You can't stop within the 250 feet your headlights light
Headlights let you see clearly about 250 feet ahead; driving faster than 55 mph at night means you can't stop within that distance.
Handbook p. 42 ↗ In very heavy rain, snow, or thick fog where you can't see more than 100 feet ahead, what should you do? Switch to high beams to see farther Pull off the road and wait until it clears Slow to 15 mph and turn on your hazard lights Follow the taillights of the car ahead Answer: Pull off the road and wait until it clears
When you cannot see further than 100 feet ahead, you cannot drive safely at any speed, so pull off the road and wait until it clears.
