Regulatory signs — Pennsylvania Permit Test

An eight-sided sign means stop: you must stop completely, check for people walking and for cross traffic, and go only when the intersection is clear. Slowing without a full stop is illegal.

The full stop is what buys you the look; a rolling stop skips the one moment you had to see anything.

you must stop completely, check for pedestrians and cross traffic to clear the intersection before you go again. Slowing down without coming to a full stop is illegal.

A three-sided sign means yield: slow down, check for traffic, give the right of way to people crossing and to approaching traffic, and stop only if you need to.

You need a big enough gap before you go, and you cannot judge a gap at full speed.

When you see this sign, you must slow down and check for traffic and give the right-of-way to pedestrians and approaching cross traffic. You stop only when it is necessary.

A do not enter sign is placed at the start of one-way streets and ramps, and means you may not drive onto that street or ramp in the direction you are heading.

Everything on the far side of it is coming at you, at full speed and not expecting you.

The DO NOT ENTER sign is put at the beginning of one-way streets and ramps. When you see this sign, do not drive onto that street or ramp in the direction you are heading.

A wrong way sign is placed further along a one-way street or ramp to catch the attention of a driver who has already turned onto it by mistake.

It is the second warning, and by then you are already pointed at oncoming traffic.

WRONG WAY signs are placed farther down the one-way street or ramp. They are placed there to catch your attention, if you accidentally turn onto the street or ramp.

A one way sign means traffic may move only in the direction the sign points.

Turning against it puts you head-on into every car on the street.

The ONE WAY sign means traffic is allowed to move only in the direction the sign is pointing.

A no U-turn sign forbids turning completely around to go the opposite way at that place.

The turn crosses every lane at once and nobody coming is expecting it.

This sign prohibits U-turns. Do not make a complete turn to go in the opposite direction.

A no right turn sign means right turns are forbidden at that intersection.

The turn is banned where the street it leads into cannot safely take the traffic.

This sign indicates right turns are prohibited. Do not make a right turn at this intersection.

A do not pass sign marks places where you may not pass any vehicle going the same direction, and it often appears with the pennant-shaped no passing zone sign.

It goes up where you cannot see far enough ahead to know the other lane is empty.

This sign may be placed in areas where you may not pass any vehicles going in the same direction.

A keep right sign directs drivers to keep to the right of a traffic island or divider.

Something solid sits in the road, and taking the wrong side of it means meeting traffic head-on.

These signs direct drivers to keep to the right of the traffic island or divider.

A speed limit sign gives the highest legal speed for that stretch of road under ideal conditions, and your safety may depend on driving slower when conditions are poor.

The number assumes a dry road in good light, and the weather does not read signs.

A SPEED LIMIT sign indicates the maximum legal speed under ideal conditions for the stretch of highway where it is posted.

Where a no turn on red sign is posted you may not turn during the red signal; you must wait for the green signal.

These go up where a turning driver cannot see somebody stepping off the curb in time.

You may not turn during the red light cycle at an intersection where one of these signs is posted. You must wait for the signal to turn green.

A ring with a slash through it always means no, and the picture inside shows what is not allowed.

One symbol does the work of a sentence, so the ban reads at a glance from far off.

Some regulatory signs are black, white and red, like the NO LEFT TURN sign with a circle and slash.

What must you do at this sign?

Stop completely, then go when the way is clear. The full stop is what buys you the look; a rolling stop skips the one moment you had to see anything.
