Who Can Drive In HOV Lane In California

by Jim on September 22, 2022

In a bid to enhance road conditions, reduce growing traffic congestion, and encourage ride-sharing, the federal highway administration in California incorporated HOV driving lanes, also referred to as High Occupancy Vehicle Lanes, on select highways. So far, the designated HOV lanes have proven effective in minimizing road congestion and ensuring maximal rider capacity.

While HOV lanes have proved to be an effective traffic management strategy seeing how instrumental they’ve been in alleviating congestion. However, there are special regulations on their usage, which drivers in California must be aware of before using them.

Read on to discover some necessary information concerning HOV lanes and what vehicles are eligible to use them in California.

What Are HOV Lanes?

In California, HOV lanes are typically reserved for two passenger vehicles, that is, the driver and one other passenger. These lanes are often found on the left side of unrestricted lanes. They can easily be identified by the diamond symbols printed on their surfaces and by road signs. At times median strips are used to demarcate unrestricted or regular driving lanes from HOV lanes.

HOV Lanes are usually operational in Northern California during traffic congestion hours, while they are operational all day long in Southern California.

Vehicles Eligible To Use HOV Lanes In California

To be granted unrestricted usage access to HOV lanes in California when they are fully operational, your vehicle must have at least two occupants. While this is the standard requirement, certain vehicles are exempted by the state highway system.

  • Specific routes in areas such as San Diego (I-5 San Ysidro), Los Angeles (I-10 and El Monte Bus Way), and San Francisco Bay area (I-80 and I-880) only permit vehicles with 3 or more occupants to make use of HOV Lanes.
  • Any clean air vehicle, vehicles that use alternative fuel, plug-in, and hybrid vehicles are all granted special access to HOV facilities in California. This simply means that such vehicles are not restricted by the above occupancy requirement. The vehicles given access privilege are identifiable by decals of the California Department Of Motor Vehicles.
  • Drivers operating public transit vehicles, plug-in hybrid vehicles, motorcycles, and para-transit vehicles are permitted to access HOV lanes and any HOV facility. They are not restricted by the occupancy requirement during on or off-peak hours.

HOV Occupancy Regulations

A few standard occupancy requirements are associated with using HOV lanes on Southern and Northern California highways. One of such requirements is that vehicles with two or more passengers present are permitted to use HOV lanes during operational hours. To be considered occupants, each passenger must use their seatbelts or any other form of safety restraining device.

To avoid ticket fines, any vehicle driving on an HOV lane in California must have the required number of passengers, which is typically indicated by traffic signs at the entrance of the HOV lanes. Usually, the signs indicate that vehicles with two passengers are allowed to use the lanes. However, there are instances whereby the minimum requirement is three passengers.

Children count as passengers. However, pets and unborn children do not. These requirements are non-negotiable, except for the vehicles as mentioned earlier, which are granted exclusive rights to use the lanes.

Lastly, vehicles that are required to drive within the 55 MPH limit, which includes trailers, towing vehicles, and trucks, are not allowed on HOV lanes whether or not they meet the occupancy requirement.

Exceptions To HOV Occupancy Rules According To The California Vehicle Code

As mentioned previously, motorcycles, clean air vehicles that improve air quality, plug-in hybrid vehicles, alternative fuel, public mass transit, and vehicles with white or green decals issued by Californian traffic authorities are not affected by the occupancy requirement during weekday congestion periods.

This simply means that drivers of vehicles with white or green decals and the aforementioned vehicles are granted free range on HOV lanes in California during the posted peak congestion hours whether they choose to drive solo or not.

Other exceptions include:

1. Part-time High Occupancy Vehicle Lanes

Part-time high occupancy lanes are deemed carpool lanes during peak congestion hours, which are usually around 6 to 10 am and 3 to 7 pm throughout weekdays. In other words, it’s not considered illegal for vehicles with single occupants to drive on these lanes outside their hours of operation, as long as passengers wear their seatbelts or safety restraint device.

Watch out for signs that are posted at the entrance of HOV lanes are they typically indicate when the lanes are carpool only, that is only accessible with the stipulated number of passengers.

2. High Occupancy Toll Roads

High Occupancy Toll Lanes, also known as HOT Lanes, grant vehicle access with single occupants so long as they pay the required toll. Payment can be made in several ways, for instance, through a prepaid Express account or electronically with a FastTrak responder.

While paying the toll will grant drivers access to any HOT Lane, vehicles limited to the 55 MPH speed limit like trailers, large school buses, and other oversized vehicles are not allowed to use them under any circumstance.

If you aren’t sure whether your vehicle qualifies to use High Occupancy Toll Lanes on California highways, the best course of action is to avoid using them altogether. Traffic congested roads can be a serious hassle, but a rather expensive HOV violation ticket is way worse.

How To Tell The Difference Between HOV And Carpool Lanes

It’s easy to tell the difference between a carpool and a High Occupancy Vehicle (HOV lanes) in California. While both of these limited access lanes are usually located on the left side of highways, signs at their entrances help drivers tell them apart. Also, California High Occupancy Vehicle Lanes are known to have white diamond lanes. These symbols can sometimes be depicted in that particular HOV corridor.

What To Do If You Get An HOV Lane Violation Ticket

Even the best of us make mistakes now and then, so there’s no need to beat yourself up about it if you end up with a ticket. Perhaps you were trying to make your way through heavy traffic only to find yourself on an HOV lane or maybe you did so intentionally but for safety reasons.

It can be extremely upsetting, especially if your reasons are justified. You’re not alone, as many others find themselves in the same situation. If you feel that the circumstances that led you to get a ticket weren’t given proper consideration, the best way to fight the ticket is by filing a written declaration through the appropriate channel.

This is practically the easiest and quickest way to contest the ticket. Also, it doesn’t require you to go to court. If your ticket gets dismissed, you don’t have to worry about getting points on your driving record.

Tips For Using HOV Lanes In California

Here are a couple of things to keep in mind when driving on HOV lanes in California:

  • In California, HOV lanes are usually located on the inside left of highways.
  • You can easily identify HOV lanes by the white diamond signs on their pavements.
  • HOV lanes in Northern California are operational only during weekdays, from 6 to 10 in the morning and afternoon commute hours. Usually, the hours of operation of HOV lanes are posted at their entrances.
  • In Southern California, regular driving lanes and HOV lanes are separated with buffers; the lanes are also operational 24/7.
  • In Northern California, traffic congestion is usually at its peak in the morning and evenings. As a result, it’s not illegal to use part-time HOV lanes outside of their operational periods.
  • Traffic congestion in Southern California takes a little longer to clear up compared to Northern California. At times the traffic congestions last for up to 11 hours each day, which is the major reason the state decided to incorporate HOV driving lanes.

Penalties For Breaking The California State Law On Car-pool Lane HOV Lane Usage

Any driver who violates carpool lane rules and HOV regulations in California is bound to get pulled over and will also be made to pay a $490 fine.

The objective of the California Highway Patrol is to ensure that High Occupancy Vehicle HOV laws are adhered to. When violations go beyond 10 percent, this HOV Lane enforcement body automatically implements stronger measures.

The Effects Of HOV Lanes On A Driver’s Injury Claims

HOV lanes significantly reduce traffic congestion, but this doesn’t change the fact that accidents can occur at anytime and anywhere.

It was recently discovered that HOV lanes where accidents are most likely to occur are 24-hour HOV lanes constructed close to on or off-ramps. If you happen to get injured in a car crash on an HOV lane, make sure to reach out to a qualified car accident attorney for advice on the best possible course of action.
