CVC 22348(c) is a lane-use provision for vehicles covered by CVC 22406. It should not be confused with the over-100-mph provision in section 22348(b). Confirm the subsection, vehicle type, and location written on your citation.

How do the designated-lane rules work?

Covered vehicles generally use a designated lane, or the right-hand lane when none is designated. The statute addresses passing and permits the lane immediately left of the right-hand lane in specified circumstances on divided highways with four or more marked lanes in one direction.

It also provides exceptions for preparing to turn, entering or leaving a highway, or necessarily using another lane to continue the intended route. Whether an exception applies depends on the facts; it is not an automatic reason for dismissal.

Does this apply only to commercial truck drivers?

No. Section 22406 covers specified vehicle types, including certain trucks and vehicles towing another vehicle. A passenger vehicle towing a trailer can therefore raise different questions from a passenger vehicle traveling alone. State your vehicle and trailer configuration when requesting help.

What information is useful?

• The citation and court notice, with the exact code and deadline.
• Vehicle type, axle or towing configuration, and license type.
• The number of marked lanes and any truck-lane signs.
• Your lane, route, and whether you were passing, turning, entering, or exiting.
• Existing dashcam footage, route records, or safe photographs that support your account.

Costs and commercial-driving concerns

Do not rely on a blanket fine, insurance increase, or point figure for every driver. The court notice, vehicle, license status, and exact conviction affect the questions to ask. Commercial drivers should specifically discuss DMV and employment implications before choosing a response.

Common questions

Is a lane-use ticket the same as a speeding ticket?

No. Section 22348(c) addresses lane use. Read every section on the citation, since separate allegations may appear together.

Does passing automatically excuse being in another lane?

No. The statute limits the lanes available for passing. Review the lane layout and circumstances rather than assuming that any lane is permitted.
