Warning signs — Pennsylvania Permit Test

The road curves ahead to the left; slow down, stay in the center of your lane, and drive through the bend.

A curve is taken by holding your lane, which is why the sign asks for less than a sharp turn does.

The road curves ahead to the left. You need to slow down, stay in the center of your lane and prepare to navigate through the left-bending curve.

This sign is placed on the left side of the road facing the driver, at the start of a stretch where passing is not allowed.

It faces the driver about to pull out, which is the one person who has to see it.

This is the only pennant-shaped warning sign. This sign marks the beginning of a no passing zone and is placed on the left side of the road facing the driver.

The road ahead turns sharply to the left, so slow down a great deal before you reach it; some sharp turn signs carry an advisory speed.

You cannot slow down safely once you are in the turn, so the braking has to be done before it.

The road ahead turns sharply to the left. You need to slow down substantially

An advisory speed sign may be used with any four-sided warning sign, and gives the highest speed you should travel through what is ahead.

The number is set for the curve, which will carry you off the road well under the posted limit.

This sign may be used with any diamond-shaped warning sign. The highest speed you should travel around a sharp left curve ahead is 25 mph.

A merging traffic sign is placed on a major road to tell you traffic may be joining your lane from another road or a ramp, and entering traffic must yield to traffic already there.

Both drivers assume the other will yield, and that shared guess puts them in one space.

Entering traffic must yield to traffic already on the major roadway.

A lane ends sign tells you one lane on a multi-lane road will end ahead and the traffic in that lane must merge over.

The lane runs out whether or not anybody makes room for you.

These signs tell you one (1) lane on a multi-lane roadway will end ahead.

A divided highway begins sign means the road ahead becomes two one-way roadways separated by a median, and you keep to the right of the divider.

Your side of the road is about to become one-way, and the other side becomes traffic coming at you.

roadways and a median or divider separating traffic moving in opposite directions. Keep to the right of the divider or median.

A divided highway ends sign means the divided road you are on is about to end and you will be on a road with two-way traffic, so keep right of the centerline.

Nobody has been coming at you, and that stops being true at this sign.

The divided highway on which you are traveling ends ahead.

A two-way traffic ahead sign means the one-way road you are on ends ahead and you will be on a road with two lanes moving in opposite directions.

Staying right of the centerline stops mattering only while nothing is coming the other way.

The one-way street or roadway ends ahead. You will then be traveling on a road with two (2) lanes of traffic moving in opposite directions.

A cross road sign shows an intersection ahead, warning you that the road you are on may not continue straight through and that other vehicles may be moving there.

Knowing the shape of the intersection early lets you slow down before you are in it.

The signs below show types of intersections. By showing you in advance how the roads join each other, the signs let you know when the road you are traveling on does not continue straight through the intersection.

A circular intersection sign warns that a roundabout or traffic circle is ahead.

The sign tells you the shape of what is coming, which is what decides how you enter it.

CIRCULAR INTERSECTION

A narrow bridge or underpass sign means each lane becomes narrower ahead and there is generally no shoulder, so slow down and stay in your lane.

The room either side of you disappears, and a wide vehicle coming the other way has nowhere to go.

Each lane on the bridge or underpass becomes narrower, and there generally is no shoulder. You need to slow down and make sure you stay in your lane.

A slippery when wet sign marks places that are especially slippery in the rain: slow down, leave more room, and do not speed up or brake quickly.

Grip is what makes the steering and the brakes work at all, and wet tar takes most of it away.

Especially slippery conditions exist when wet. In wet weather, reduce your speed and increase your following distance. Do not accelerate or brake quickly.

A deer crossing sign is posted where deer often cross and crashes with deer have happened.

Where one deer crossed, others usually follow within seconds.

This sign is posted in areas where deer frequently cross and crashes with deer have occurred.

A hill or downgrade sign means a steep hill is ahead: slow down and be ready to shift to a lower gear to control your speed and save your brakes.

Brakes that get hot on a long grade may have nothing left at the bottom.

There is a steep hill ahead. Slow down and be ready to shift to a lower gear to control your speed and to save wear and tear on your brakes.

A traffic signal ahead sign means a signal is at the intersection ahead that you may not be able to see because of a bend or hill, and a line of vehicles may already be stopped there.

The line of stopped cars behind an unseen signal is what you actually hit.

A traffic signal is present at the intersection ahead. You may not be able to see it because of a curve or hill.

A stop sign ahead sign means a stop sign is at the intersection ahead that a bend, hill or other obstruction may be hiding, and vehicles may already be stopped there.

It gives you the seconds you would otherwise spend discovering the stop sign at close range.

A STOP sign is present at the intersection ahead. You may not be able to see it because of a curve, hill or something else blocking your view.

A bicycle crossing ahead sign means cyclists may be crossing your path, so be ready to slow down.

A bicycle is narrow enough to disappear into your blind spot and stay there.

Bicyclists may be crossing your path ahead. Be prepared to slow down, if necessary.

A pedestrian crossing sign is used at a marked crosswalk, or before places where people may be crossing your path.

Someone on foot has nothing around them, so the whole cost of the mistake lands on them.

Used at a marked crosswalk or in advance of locations where pedestrians may be crossing your path.

This sign means you are approaching a school zone; with a downward arrow beneath it, it marks the school crossing itself.

Children step out without checking, and a parked car hides someone that short completely.

This is the only pentagon-shaped sign used on the roadway. It means you are approaching a school zone.

What does this sign tell you the road does ahead?

It curves to the left. A curve is taken by holding your lane, which is why the sign asks for less than a sharp turn does. PA Driver's Manual, p.13: “The road curves ahead to the left. You need to slow down, stay in the center of your lane and prepare to navigate through the left-bending curve.”
