Interchanges — North Dakota Permit Test

The two most common types of interchanges are the diamond and the cloverleaf.

Knowing the shape ahead tells you where the ramps will be and when you must be in the right lane.

The two most common types of interchanges are the diamond and the cloverleaf.

Highway guide signs tell you where interchanges are well in advance; move into the proper lane before you reach your interchange.

A late lane change at highway speed near a ramp is how drivers cut each other off and crash.

Move into the proper lane before you reach your interchange.

Never back up on the Interstate; if you miss your interchange, go on to the next one.

A car backing up against highway traffic is in the path of drivers moving fast who do not expect it.

If you miss your interchange, go on to the next one.

Do not use median crossovers; they are for authorized vehicles only, such as emergency and maintenance vehicles.

Crossing the median puts you across lanes of fast traffic from both directions at once.

These are for authorized vehicles only such as emergency and maintenance vehicles.

If you exit at the wrong interchange, you must follow it out and return to the highway by the on ramp.

Backing up on a ramp puts you against traffic that is coming off the highway at speed.

Return to the highway by the “on” ramp.

Entrance ramps let you adjust your speed to merge; avoid stopping on them, and stop only when there is no opening in traffic.

A car stopped on a ramp must merge from a standstill into fast traffic, and the car behind may not expect the stop.

Only stop when there is no opening in the traffic flow.

Unless signs say otherwise, a vehicle entering a freeway from an entrance ramp must yield the right of way to vehicles on the main roadway.

Cars on the freeway are moving fast and cannot stop for you, so the merging driver fits into a gap.

Unless posted signs indicate otherwise, any vehicle entering a freeway from an entrance ramp must yield the right of way to vehicles on the main roadway.

Exit ramps are for leaving the highway, and you should never stop or back up on them.

Drivers coming off the highway are still going fast and will not expect a car stopped or reversing on the ramp.

You should never stop or back up on these ramps.
