What does the steep hill warning sign mean?
A steep hill is ahead. Control your speed and consider a lower gear
This sign warns of a steep hill ahead. Control your speed on the downgrade. You may need to shift to a lower gear so you are not relying on your brakes alone.
Why the other answers are wrong
-
A truck entrance is ahead
The truck entrance sign shows a truck joining from the side of a level road. Here the truck is tipped down a slope with a grade percentage, so the hill is the hazard.
-
Trucks are not allowed ahead
A ban would come on a regulatory sign, usually square or rectangular, with a red circle and a slash through the symbol. A yellow diamond does not ban anything, it warns you about a hazard ahead, here the slope.
-
A weigh station is ahead
Facilities and services are pointed out by rectangular information and direction signs. A yellow diamond never points to a building. It describes the road condition coming up, in this case a downgrade.
Quick way to remember
The vehicle on the sign is pointed downward.
