An on-ramp is a short road or entrance ramp that allows vehicles to merge onto a highway or freeway from a smaller road or street. It is designed to give drivers enough space to accelerate and safely enter the faster-moving traffic on the main road. On-ramps are typically located at intersections or exits and help connect local roads to larger highways, ensuring smooth traffic flow and easier access for drivers entering high-speed roads.
