The posted limit is the fastest you may go on a good day, not the speed you must drive in bad weather.

A yield sign means slow down and yield the right of way to traffic in the intersection or roadway you are entering.

A yield sign means you must slow down and yield the right of way to traffic in the intersection you are crossing or roadway you are entering.

A one-way sign means traffic moves only in the direction of the arrow.

Driving against the arrow puts you head-on with every car on that street.

A do not enter sign marks a roadway opening you must not enter.

Going in past this sign would put you on a road where traffic comes straight at you.

You will see this sign at roadway openings you are not to enter.

Do not enter signs are found at exit ramps, crossovers on divided roadways, and many places on one-way roads.

These are the spots where a wrong turn sends you against traffic, so the sign stands there to stop you.

You will see them at exit ramps, in crossovers on divided roadways, and at numerous locations on one-way roads.

A wrong way sign means you made a wrong turn into a lane of oncoming traffic; get off the traveled road, stop, and turn around as quickly and safely as you can.

Every second in that lane you face cars coming at you, so get out of their path fast but safely.

You made a wrong turn and have entered a lane of oncoming traffic.
