Road defects and cyclists

Start with the deadline, because it is what loses these claims. A claim against a public entity must be presented within six months of the injury, not two years. People spend the first months treating, assume they have time, and find the door shut. This is general information, not legal advice.

The defects that put cyclists down

• Potholes and edge breaks, particularly where a bike lane meets a deteriorating gutter pan.
• Drainage grates with slots running parallel to travel, which can swallow a front wheel. A known hazard with a known fix.
• Longitudinal seams and joints, including the gap between an old surface and a new one, which can catch and steer a wheel.
• Uneven repaving — a height difference between the travelled lane and the bike lane during resurfacing.
• Steel plates over trenches, unramped or unsecured.
• Raised or sunken utility covers.
• Debris and gravel allowed to accumulate in a bike lane that is not swept.
• Missing or obscured signage and markings, including a lane that ends without warning.

The common feature is that a car passes over all of these without the driver noticing. A bicycle has two narrow contact patches and depends on them for balance.

The dangerous-condition claim

A public entity is liable for injury caused by a dangerous condition of its property where the plaintiff establishes that the property was in a dangerous condition at the time of the injury, that the injury was proximately caused by the condition, that the condition created a reasonably foreseeable risk of the kind of injury incurred, and either that a negligent or wrongful act of an employee within the scope of employment created it, or that the entity had actual or constructive notice of it a sufficient time before the injury to have taken protective measures.

Sources: Gov. Code, § 835 (dangerous condition of public property); § 911.2 (six months to present a claim); § 945.6 (six months to sue after a written rejection).

Notice is where these cases are won or lost

Establishing that the entity knew, or should have known, is the substance of the claim. What builds it:

• Prior complaints and service requests — 311 records, emails, and council correspondence.
• The entity's own inspection schedules and records for that street.
• Maintenance work orders opened and not completed.
• Prior collisions or reported near misses at the same location.
• How long the defect had visibly existed — weathering, vegetation growth in a crack, wear patterns.
• Any prior repair at the same spot, which shows the entity was aware of the location.

Most of this is obtainable through public records requests, and those should go out early — alongside the claim, not after it.

Design immunity

The recurring obstacle. A public entity may be protected where the feature was part of a plan or design approved in advance by a body or employee with discretionary authority, and there is substantial evidence supporting its reasonableness.

Two things follow for a cyclist's claim. It matters enormously whether the hazard is a design feature or a maintenance failure — a pothole, an accumulation of debris, and a raised utility cover are not design choices, and the immunity does not naturally reach them. And where an approved design has produced a pattern of collisions, the argument shifts to whether the entity had notice that the design was not working in practice.

Photograph it before it is repaired

Road defects get fixed, sometimes within days of a reported injury, and a repaired defect is very difficult to prove. The repair is useful evidence of knowledge — but only if you can show what was there.

• Photograph the defect with something for scale, from several angles and from riding height.
• Photograph the approach as a rider would see it, which shows what was and was not visible.
• Record the precise location — coordinates, nearest address, direction of travel.
• Note contractor names and permit numbers on any plates, cones, or boards.
• Return within days and photograph again to establish whether and when it was repaired.
• Keep the bicycle unrepaired; wheel and fork damage corroborates the mechanism.

Not only the public entity

A contractor doing roadworks, trenching, or paving can be liable on ordinary negligence principles — and without the six-month claim deadline. So can a utility that left a cover proud of the surface, or a private site that tracked gravel onto the carriageway.

The same problem from a motorcycle, where the hazard set differs: road hazards and riders.

Common questions

Can I claim against a city for a pothole?

Possibly. A public entity is liable for injury caused by a dangerous condition of its property where the condition created a reasonably foreseeable risk of that kind of injury and the entity either created it or had notice long enough beforehand to protect against it. Notice is usually the fight.

How long do I have?

Six months to present a claim to the entity, not two years. That is the single most important fact on this page and the most common reason these claims fail.

The defect was repaired right after my crash. Have I lost the evidence?

Only if you did not photograph it. The repair itself can support the argument that the entity knew about the problem — but you need to show what was there beforehand, which means photographs taken before the work.

They say a careful cyclist would have avoided it.

Expect it, and answer it with geometry. Seams and grate slots are not visible at riding speed, a pothole in shadow is invisible until it is under the wheel, and a rider watching for traffic is doing what safety requires. Any share reduces rather than bars the claim.
