Warning signs — Utah Permit Test

This sign warns that a stop sign is ahead.

It is posted where the stop itself comes into view too late, on a curve or over a rise.

Stop Sign Ahead

This sign warns that a traffic signal is ahead.

Knowing a signal is coming is what lets a driver lift off early rather than brake hard on a yellow.

Traffic Signal Ahead

This sign warns that a lane is ending ahead.

The lane running out is the one you are in. Merging early beats arriving at the point where it disappears.

Lane Ends

This sign warns that traffic is merging into the roadway ahead.

Two streams of traffic are about to become one, and both of them think the other should wait.

Merging Traffic

This sign warns of a curve to the right ahead.

The plate tells you which way to expect the road to go, so the steering is decided before the curve arrives.

Right Curve

This sign warns that an intersection is ahead.

A crossing road is where traffic arrives sideways, and sideways is the impact a car protects you from least.

Intersection Ahead

This sign marks the start of a zone where passing is not allowed.

It is posted on the driver’s left, facing the traffic that might be tempted to pull out and pass.

No Passing Zone

This sign gives the advised speed for a curve ahead.

It is not the posted limit but the speed somebody measured the curve at, usually with a truck in mind.

Advisory Speed Around Curve

This sign warns of a school crossing ahead.

Children judge speed and distance badly and step out without looking. A school crossing is where most of them are.

Stop and yield as signaled at school crossings where there is a traffic patrol.

This sign warns of a pedestrian crossing ahead.

It marks a place people cross away from a signal, which is exactly where a driver is not expecting anybody.

Pedestrian Crossing

This sign warns that bicycles cross or share the road ahead.

A bicycle is narrow, quiet and easy to lose against a hedge. The sign is the warning to start looking.

You must be alert for bicyclists and be extra careful when approaching them.

This sign warns that the road ahead is slippery when wet.

Some surfaces lose grip far faster than others in rain, and there is no way to tell by looking at them.

Slippery When Wet

This sign is placed where there are many animal and vehicle collisions, and warns a driver to be alert for animals.

Utah posts these where the crashes already happen, so the sign is a record rather than a guess.

Being alert when driving on roadways marked with animal crossing signs.

This sign warns of a steep hill ahead, where a driver should pay special attention to speed and use a low gear.

Gravity does the accelerating on a long descent, and brakes that are ridden all the way down stop working.

Pay special attention to speed limit signs and warning signs, such as warnings about curves, steep hills, or other hazards.
