What is the speed limit on a ramp?
1 Answers
On highways, the speed limit within ramps is generally required to be below 40km/h. This speed restriction is established based on the safe driving speed determined by the ramp's turning radius. Before entering the ramp, turn signals should be turned off, and the speed should be controlled to reduce below the marked limit. Highway ramps are right-side lanes at highway exits or entrances, typically ranging from 150 to 200 meters in length. After the entrance ramp is the acceleration lane, while the exit ramp immediately follows the deceleration lane. The ramp surface is designed with the outer side higher than the inner side to partially counteract the outward tilt caused by centrifugal force, which is particularly beneficial for taller vehicles. Important considerations for driving on highway ramps include: Pay attention to road signs along the way. On highways, be sure to notice directional signs posted along the roadside well before the ramp entrance. Avoid last-minute actions like stopping at the ramp entrance to check directions. If missed, continue forward. If you're too close or have already passed the ramp entrance, never brake suddenly or reverse, as following vehicles traveling at high speeds may not have enough time to avoid a collision, potentially causing a rear-end accident. Use the "side lane" when entering or exiting ramps. Since most ramps have a 40 km/h speed limit, highways provide a "side lane"—either a deceleration or acceleration lane—alongside the main travel lane to allow safe speed transitions. These are separated from the main lanes by short, thick, conspicuous white markings.
