Do I have to stop at highway on-ramp meters? Can I get a ticket? What CA law says
Whether you’re heading to work or starting a road trip, you might notice an on-ramp meter telling you when to merge — or when to wait — before entering a California highway.
How do on-ramp meters work? Can you get a ticket for not stopping?
Here’s what California law says:
How do on-ramp meters work in California?
Ramp meters are traffic lights on highway entrances designed to make roads safer and reduce congestion, according to the California Department of Transportation.
Many factors are taken into consideration to determine the location of on-ramp meters, including highway capacity and peak traffic periods in the morning and afternoon, the state transporation department previously told The Sacramento Bee.
The system automatically adjusts how long you wait based on traffic conditions.
This means during heavy traffic or backups from crashes or construction, you might wait a bit longer, said Nick Liccardo, a senior transportation engineer with the state Transportation Department.
Sensors in the road help the system monitor congestion and manage the flow.
When are highway on-ramp meters active in California?
Once traffic reaches certain levels, on-ramp meters will turn on, the California Department of Transportation said.
These meters can activate at any time — including weekends and holidays — whenever congestion builds up.
An illuminated sign at the ramp entrance lets drivers know when the meter is in use.
Do I have to stop before entering the highway?
When the meter is active, a red light signals that a driver must stop before entering.
A green light signals for a driver to continue through.
Most meters let one car go per green light, although some allow two.
Can I get a ticket for not stopping at a ramp meter?
According to California’s Vehicle Code, you do not have to stop and cannot be ticketed if the ramp meter is off and there’s no red light.
However, you can be cited if you do not stop at an on-ramp meter signaling a red light.
If you run a red light at a ramp meter, you could be cited under California law, which requires drivers to stop at a steady red signal — even at a highway on-ramp, the California Highway Patrol previously told The Bee.
What are penalties for running a red light in California?
According to the Judicial Council of California’s Uniform Bail and Penalty Schedule, running a red light carries a $100 base fine. After additional court fees and penalty assessments, the total cost can reach nearly $500.
Running a red light can also add one point to your driving record, according to Shouse California Law Group in Southern California.
In California, if a driver racks up a certain number of points on their record within one, two or three years, the California Department of Motor Vehicles can label them a negligent operator and suspend or even revoke their license.
Can I drive through red light if it won’t turn green?
Caltrans often gets complaints from drivers saying the onramp traffic light won’t turn green, Liccardo said.
This typically happens because the driver has pulled too far forward for the sensor to detect their vehicle.
If the light has been red for a while, Liccardo said, it’s okay to go ahead and proceed if it is safe to do so.
