Commercial fleets across Orange County face constant pressure to keep trucks compliant, operational, and ready for a CHP inspection. Some of that pressure is proactive, catching worn parts before they become a problem. Some of it comes after the fact, a truck already failed and needs repair before it can pass re-inspection. Alignment Express handles the mechanical side of both situations.
Contact Alignment Express to get a truck repaired or checked over.
Who Performs a CHP Vehicle Inspection, and Does Alignment Express Do It?
CHP officers and certified inspectors conduct the inspection itself, whether roadside, at a CHP facility, or during a scheduled terminal visit. A commercial driver must stop at any CHP facility posting inspection signs. Alignment Express is not certified to perform CHP inspections and has no role in issuing or clearing an out-of-service order.
What the shop does instead is repair work, on both sides of an inspection. Regular steering, suspension, axle, and frame maintenance lowers the odds of a defect turning up in the first place, and when a truck has already failed, Alignment Express repairs the specific issue an inspector flagged so it’s ready for re-inspection.
What Alignment Express Doesn’t Cover
Brake systems and lighting are handled by a separate shop. A complete repair plan, whether preventive or after a failed inspection, usually pairs Alignment Express’s front-end and frame work with a brake and lamp shop for those systems.
What CHP Checks During a Commercial Vehicle Inspection
CHP inspections are documented against the California Vehicle Code, often on the CHP 108 truck and tractor maintenance and safety inspection form, which the CHP Commercial Vehicle Section publishes alongside its other carrier compliance forms. The inspector works through brakes, steering linkage, suspension components, tires, wheels, lamps, and the frame.
A defect serious enough to make the truck unsafe under load puts the vehicle out of service until it’s repaired and verified.
The Terminal Inspection Program and the 2025 Weight Change
California also reviews vehicles and maintenance records at the carrier’s terminal rather than at a scale, a program historically called Basic Inspection of Terminals. Under the 2025 rule change limiting the 90-day terminal cycle to heavier vehicles, only vehicles with a gross vehicle weight rating of 26,001 pounds or more remain on that mandatory cycle as of January 1, 2025.
Lighter vehicles moved to the federal annual inspection standard under 49 CFR 396.17, unless they haul placarded hazmat, carry ten or more passengers, or tow a heavy trailer.
Keeping Steering, Suspension, Axle, and Frame Issues From Causing a Failure
A regular maintenance visit checks the front end on the Hunter Hawkeye XL, which reads every axle at once rather than one wheel at a time. That catches a rear axle pushing the truck crooked at the same time as a worn steering component up front, before either one becomes a citation.
Most alignment and suspension repairs are completed the same day at the Irvine facility. Frame and axle work that needs a full bay gets scheduled around the fleet’s route calendar so a truck isn’t parked longer than necessary.
My Truck Failed a CHP Inspection, Now What?
A failed inspection on the steering, suspension, axle, or frame system needs to be repaired and verified before the truck passes re-inspection. Alignment Express handles that repair work directly, diagnosing the specific defect an inspector flagged and fixing it rather than replacing parts on a guess.
Kingpin replacement is the single most common repair Alignment Express performs as a result of a failed inspection. A worn steering kingpin creates the loose, wandering front end that draws a citation, and once it’s pressed and the alignment is reset, the truck is ready to go back for re-inspection.
Alignment Express stocks the kingpin sets, bushings, and steering components this repair takes as part of its full services lineup.
Other Common Post-Failure Repairs
Beyond kingpins, the repairs that most often follow a failed inspection include worn steering linkage, sagging or cracked leaf springs, a bent axle, and frame straightening. Each of these can independently cause the loose steering or crooked tracking an inspector checks for.
Getting a Truck Cleared After a Failed Inspection
A truck marked out of service can’t be operated, including towing it under its own power, until every item on the out-of-service notice is repaired. This is a federal requirement under 49 CFR 396.9, not a CHP-specific rule, so it applies regardless of which agency issued the order.
Once Alignment Express completes the repair, the motor carrier or a qualified mechanic certifies the work was done, and that certification typically needs to reach the issuing agency within 15 days. A truck that earns a clean Level I inspection afterward can also receive a CVSA decal, which is valid up to three consecutive months and generally exempts the vehicle from re-inspection during that window.
Signs Your Truck Needs Steering, Suspension, Axle, or Frame Work
Some warning signs show up well before an inspector finds them, and each one points to a different system.
Steering and Alignment
A truck pulling to one side while driving usually means an alignment or steering issue. Loose or delayed steering response signals worn linkage that will only get looser with more miles on it.
Suspension
A sagging ride height, visible spring damage, or a rougher ride than usual points to suspension wear. Left alone, worn suspension components accelerate tire wear and put more stress on the axle underneath.
Axle and Frame
Uneven or rapid tire wear usually traces back to axle or suspension misalignment. A truck that tracks crooked down a straight road, or shows visible cracking near the frame rails, often has a bent axle or frame problem that won’t show up as a simple alignment fix.
Any of these is worth a repair visit whether the truck is due for inspection or already failed one.
Roadside Inspections vs. Terminal Inspections in California
A roadside inspection happens whenever CHP stops a truck on the road or at an open inspection facility, checking the vehicle and driver on the spot. A terminal inspection instead reviews a carrier’s vehicles and records at the terminal itself.
Terminal inspections cover vehicles at or above 26,001 pounds GVWR, along with vehicles hauling placarded hazmat, carrying ten or more passengers, or pulling heavy trailers regardless of weight.
Recordkeeping for Terminal Inspections
Covered carriers must identify their inspection terminals and keep vehicle inspection and maintenance records on file, generally for at least two years, under the recordkeeping requirement set out in California Vehicle Code Section 34501.12.
A mechanically sound fleet with disorganized paperwork can still run into problems at a terminal review. Keeping repair records alongside the truck’s maintenance file matters as much as the repair itself.
Agricultural Vehicle Exemption
Agricultural vehicles carry their own exemption from this program. Under AB 525’s extension of the agricultural vehicle exemption, vehicles weighing 26,000 pounds or less, operated by a farmer for agricultural use and not for hire, stay exempt from the terminal inspection requirement through January 1, 2031.
What Puts a Commercial Vehicle Out of Service
Not every defect automatically pulls a truck off the road. Out-of-service determinations follow the North American Standard Out-of-Service Criteria that the Commercial Vehicle Safety Alliance updates every year, a pass-fail standard rather than a fixed checklist.
The 2026 edition took effect April 1, 2026, and includes seventeen changes covering items from brake measurements to wheel and rim defects. A worn part that drew a citation last year may fall under a different threshold this year, which is part of why a truck that failed on last year’s fix should be repaired against the current standard, not the old one.

Frequently Asked Questions
What does a CHP inspection check on a commercial truck?
A CHP inspection checks a commercial truck’s brakes, steering, suspension, tires, wheels, lamps, and frame against the California Vehicle Code, often documented on a CHP 108 form. A defect serious enough to make the truck unsafe under load puts it out of service until repaired and verified.
Does Alignment Express perform CHP inspections?
No. CHP personnel perform the official inspection, and Alignment Express isn’t certified to conduct one. The shop repairs the steering, suspension, axle, and frame issues that cause a truck to fail, both ahead of an inspection and after one.
What happens if my truck fails a CHP inspection?
A failed truck needs the flagged defect repaired and verified before it can pass re-inspection. Alignment Express diagnoses and repairs the specific steering, suspension, axle, or frame issue, with kingpin replacement being the most common repair that results from a failed inspection.
Which California vehicles are subject to terminal inspections?
As of January 1, 2025, the mandatory 90-day terminal inspection cycle applies to vehicles at or above 26,001 pounds GVWR, plus vehicles hauling placarded hazmat, carrying ten or more passengers, or towing a heavy trailer. Lighter vehicles follow the federal annual inspection standard instead.
What records do fleets need for a terminal inspection?
Covered carriers must identify their inspection terminals and keep vehicle inspection and maintenance records on file, generally for at least two years. A mechanically ready truck with missing paperwork can still create problems during a terminal review.
What can put a commercial vehicle out of service?
Out-of-service determinations follow the North American Standard Out-of-Service Criteria, updated annually and effective April 1 each year. The current edition includes seventeen changes, so a defect is judged against the current year’s standard rather than a fixed list.
Which Orange County areas does Alignment Express serve?
Alignment Express serves the greater Orange County area from its Irvine facility at 16401 Construction Cir W, with mobile laser alignment reaching fleets across the region. The shop handles steering, suspension, axle, and frame repair, including kingpin replacement, with most work completed the same day.
