Is it permissible to stop on a freeway on-ramp?

Stopping on a freeway on-ramp is not permissible due to safety concerns. Freeway on-ramps are designed for merging traffic to enter the freeway at a speed that matches the flow of existing traffic. Stopping on these ramps can create significant risks, as drivers behind you expect a smooth transition onto the freeway. If a vehicle is stopped, it can lead to confusion and potential collisions, particularly if other drivers are not expecting a vehicle to be stationary in that area.

In addition to safety concerns, stopping on an on-ramp could impede traffic flow and disrupt the orderly merging of vehicles. Traffic laws generally require that drivers remain in motion unless they are experiencing mechanical failure or some other emergency that would necessitate stopping. In these scenarios, stopping on the freeway on-ramp should only occur as part of addressing an urgent issue, which aligns with the idea of emergencies being an exception to the general rule against stopping. However, for regular driving situations, particularly those that involve merging onto busy highways, stopping is not allowed.
