62. Ramp
A ramp is a connecting road that allows vehicles to enter or leave another road, especially a motorway, expressway or other grade-separated road. Ramps are commonly used at interchanges to connect roads without requiring traffic to cross directly at the same level.
An entrance ramp leads traffic onto the main road, while an exit ramp leads traffic away from it. Drivers should follow the signs and road markings, adjust their speed and watch carefully for merging or diverging traffic.

How should you use a motorway entrance ramp?
Follow the signs and road markings, use the ramp to adjust your speed to the traffic on the motorway and merge only when it is safe and permitted. The exact priority rules depend on the country.
