1. Exit
An exit is a designated route or point where traffic leaves a road, motorway, expressway or other major route. On high-speed roads, an exit usually leads from the main carriageway onto an exit lane or ramp that connects with another road or destination.
Drivers approaching an exit should follow the direction signs and road markings, move into the appropriate lane in good time and adjust their speed as necessary after leaving the main traffic flow.
Can you leave an Austrian motorway through an unmarked service connection?
Ordinary drivers must use the signposted exit roads.
