This sign is on the left side of a two-way highway. It warns of the beginning of a no passing zone.

This sign means the road surface is slippery when wet and is often placed near bridges and overpasses.

A bridge deck freezes before the road does, because there is cold air underneath it as well as above.

Slippery Road The road surface is slippery when it is wet. This sign is often located near bridges and overpasses.

This sign means the road ahead declines steeply, so make sure your brakes are in working order.

A long descent is where brakes overheat, and the time to find that out is before you start down.

Steep Hill The road ahead declines steeply. Make sure your vehicle’s brakes are in working order before you proceed.

This sign means two lanes will become one, and the vehicles in the ending lane must merge and yield.

Somebody has to yield, and it is the driver whose lane is disappearing.

Lane Ends Two lanes will become one. In this example, vehicles in the right lane must merge into left-lane traffic. Right-lane vehicles must yield.

This sign means vehicles will merge onto the road you are traveling on, so be ready to let them in.

They are arriving at speed with a lane that runs out, and the only room is the gap you leave.

Merging Traffic Vehicles merge onto the roadway on which you are traveling. Be prepared to allow vehicles to enter.

This sign means the bridge ahead is narrower than the road you are on.

The shoulder disappears at the abutment, so there is suddenly nowhere to go sideways.

Narrow Bridge The bridge ahead is narrower than the roadway.

This sign means you are leaving a one-way road and entering a two-way road, so stay to the right.

The lane you have been using freely is about to have somebody coming the other way in it.

Two-way Traffic Ahead You are leaving a one-way road and entering a two-way road. Stay to the right.

This sign means the road is dividing ahead, so stay to the right.

From here the two directions run on separate roadways, and the wrong one is a head-on lane.

Divided Highway Begins The road is dividing. Stay to the right.

This sign means the divided road ends ahead and two-way traffic will no longer be separated by a center island.

The island that has been keeping oncoming traffic away simply stops.

Divided Highway Ends The divided road ends ahead. Two-way traffic will no longer be divided by a center island.

This sign means the road ahead changes direction sharply, so slow to a safe speed.

A sharp change takes more grip than a gentle bend, and the grip runs out without warning.

Road Turns Ahead The road ahead sharply changes direction. Slow to a safe speed.

This sign means the road curves in the direction shown, and where a speed is posted with it, slow to that speed.

The posted speed is for the curve, not the road, and it assumes the surface is dry.

Curve The road curves in the direction indicated. If the sign displays a speed limit, slow to the indicated speed.

This sign means a roundabout is ahead, so slow to the advisory speed and be ready to stop.

You arrive needing to yield, and arriving too fast is how a driver ends up entering when they should not.

Roundabout As you approach a roundabout slow down to the advisory speed and prepare to stop if necessary.
