What is the speed limit on highway ramps?

[Carole]

Ramp speed is generally required to be below 40km/h, while the acceleration lane should quickly accelerate to above 60km/h. Here are some introductions about ramps: 1. Basic definition: A ramp, also known as an approach, is a term in engineering that usually refers to a short section providing vehicle access to main highways, elevated roads, bridges, and traffic tunnels, connecting them with adjacent service roads or other main roads via overpasses/sloped roads/approach roads, as well as collector-distributor roads and other auxiliary connecting sections. 2. Highway ramp: It is a road on the right side of a highway exit or entrance (generally 150-200 meters in length).
