Highway ramps are roads located on the right side of highway exits or entrances (generally 150-200 meters in length). Ramps, also known as approach roads, are engineering terms. After the entrance ramp is the acceleration lane, while the exit ramp follows the deceleration lane. The speed limit on ramps is generally required to be below 40km/h, and vehicles should rapidly accelerate to over 60km/h in the acceleration lane. Related details are as follows: Definition of highway ramps: Highway ramps typically refer to short sections that provide vehicle access to and from main highways, elevated roads, bridges, and tunnels, connecting to adjacent service roads or other main routes via overpasses/slopes/approach roads, as well as collector-distributor roads. They are essential traffic infrastructure components of highway interchanges. Parking is prohibited on highway ramps. Precautions when driving on highways: When entering the starting point of a highway, vehicles should quickly accelerate to over 50km/h; vehicles entering the highway from a ramp must increase their speed in the acceleration lane. Test driving and instructional driving are prohibited, as are overtaking and parking on ramps. When exiting the highway via a ramp, drivers must activate the right turn signal in advance, enter the deceleration lane, and then exit via the ramp. If an exit is missed, drivers must continue to the next exit before leaving the highway.
