§ 21664 Freeway Access Ramp Rules

This law says you can only get on or off a freeway using the special ramps made for that. You can't just drive onto or off the freeway anywhere you want.

Key Takeaways

  • •Always use the on-ramp to enter a freeway.
  • •Always use the off-ramp to exit a freeway.
  • •Never try to enter or exit a freeway by driving over grass, dirt, or any other place that's not a ramp.
  • •This rule is to keep everyone safe and avoid crashes.

Example

You're driving on a busy freeway and see your exit coming up, but you're in the wrong lane.

If you try to exit by cutting across the grass or a dirt path instead of using the exit ramp, you're breaking this law. You could get a ticket or cause a crash.
