Hit After Dark in California: The 'I Didn't See You' Excuse

You were walking or riding home after dark, a car hit you, and the driver's first words were "I didn't see you." By the time the adjuster calls, that sentence has become the theory of the case: it was dark, you were hard to see, nobody is really to blame. This post explains why California law treats "I didn't see you" as an admission more often than an excuse, what your own visibility does and does not change, and what evidence to lock down before it disappears.

The evenings are about to get darker

Daylight saving time ends at 2 a.m. on Sunday, November 1, 2026, according to NIST. The next evening, the Bay Area's commute home happens an hour closer to full dark.

That shift has a measurable cost. An IIHS study of fatal crashes in the five weeks before and after each time change from 2010 to 2019 found that fatal crashes involving pedestrians and bicyclists rose 13% after the fall change. In April 2025 Senate testimony, IIHS President David Harkey put it simply: "pedestrians and bicyclists are at greater risk in low light conditions."

San Francisco is heading into this stretch with numbers already moving the wrong way. SFist, citing an SFMTA report, says serious collisions were up 8% in the first half of 2026, and Walk SF counted 12 pedestrian deaths by early August, compared with nine at the same point in 2025.

In California, darkness is a legal condition with rules attached

Vehicle Code § 280 defines "darkness" as any time from one-half hour after sunset to one-half hour before sunrise, plus any other time when a driver cannot clearly see a person or vehicle on the road from 1,000 feet away. Once it is dark under that definition, specific duties kick in:

• Lights on. Section 24250 says that during darkness a vehicle "shall be equipped with lighted lighting equipment," and § 24400(b) requires a car to be driven in darkness with at least two lighted headlamps.
• Speed for what you can see. The basic speed law, § 22350, bars driving at a speed "greater than is reasonable or prudent," and visibility is one of the conditions the statute lists. A driver who cannot stop within the distance their headlights reveal will have a hard time calling that speed reasonable, whatever the posted limit says.
• Crosswalks do not switch off at sunset. Section 21950 still requires drivers to yield to pedestrians in marked and unmarked crosswalks, and to use "all due care" when approaching one. Section 21954(b) keeps the driver's duty of due care even when a pedestrian is crossing outside a crosswalk.

When a driver breaks one of these safety statutes and injures the kind of person it protects, Evidence Code § 669 presumes the driver was negligent. A pedestrian in a crosswalk at night is exactly who § 21950 protects. A driver running without headlights has handed you a specific violation, not a general argument about carelessness.

Why "I didn't see you" often helps your claim

Read the sentence slowly. The driver is saying they were moving a car through an area where people walk and ride, at night, without seeing what was in front of them. That raises obvious questions:

• Were their headlights on, aimed correctly, and clean?
• How fast were they going for the distance the headlights covered?
• Were they looking at a phone, a navigation screen, or the car ahead instead of the road?
• Was the windshield fogged, cracked, or glared over?

California does not let a driver off because conditions were hard. It asks whether the driver used reasonable care under the conditions that actually existed, and darkness is one of those conditions. A driver is expected to know night driving demands more attention, not less. We made the same point about the weather excuse in rain accidents.

What about your dark clothing?

Expect this argument. Adjusters raise it in night pedestrian claims, sometimes in a recorded statement where you are asked what color your jacket was.

Here is where it actually lands. The pedestrian right-of-way rules in § 21950 and § 21954 say nothing about the color of your clothes. What they do require is that pedestrians use due care for their own safety, so an insurer can argue that a dark outfit on an unlit road contributed to the crash. That is an argument for reducing your share, not for wiping out your claim, and it tends to carry the most weight when the driver did everything else right. It carries far less when the driver was speeding, distracted, or running dark.

Cyclists are in a different position because the law is specific. Section 21201(d) requires a bicycle ridden in darkness to have a white front light visible from 300 feet, a red rear reflector or light visible from 500 feet, white or yellow reflectors on the pedals, shoes, or ankles, and side reflectors (reflectorized tires count instead). A rider-worn white light can replace the bike-mounted front lamp. Electric bicycles must have the rear light or reflector at all times, not just at night. If you were missing required equipment, the insurer will use it. Whether it actually caused the crash is a separate question, and it is worth answering rather than conceding.

When the street itself was dark

Sometimes the problem is not only the driver. A streetlight that has been out for weeks, a crosswalk with no lighting, overgrown trees blocking a fixture. Government Code § 835 makes a public entity liable for a dangerous condition of its property when the condition created a foreseeable risk of the injury and the entity either created it or had notice in time to fix it.

Notice is usually the battleground, and outage reports, 311 complaints, and repair records are how it gets proven. If a city, county, or Caltrans may share the blame, the six-month government claim deadline applies.

What this means in California

• Pure comparative negligence. If a jury finds you partly at fault for your clothing, your route, or a missing bike light, your recovery is reduced by your share. It is not barred.
• Two years, generally. Code of Civil Procedure § 335.1 gives you two years from the date of injury to file a personal injury lawsuit.
• Six months against a public entity. A government claim for a dangerous road condition or a city vehicle is usually due within six months.

Evidence that disappears fastest at night

Night crashes have fewer witnesses and worse photos, so what does exist matters more.

• Go back at the same hour. Photograph the scene at the same time of night, from the driver's approach, showing what lighting there was and was not.
• Note every light that was out. Streetlights, crosswalk beacons, store signs. Report them, and keep the confirmation, because the report itself becomes evidence.
• Ask for video quickly. Doorbell cameras, businesses, buses, and dashcams often overwrite footage, so ask within days, not weeks.
• Keep what you were wearing and riding. Do not wash the jacket or throw away the bike light. A light that still works is easier to show was on.
• Get the police report and check what it says about headlights, lighting, and where you were.

Practical next steps

Get medical care now and keep your follow-up appointments, because a gap in treatment will be used against you no matter how dark it was. Write down where you were, which direction the car came from, and what lighting you remember while it is still fresh, and do not guess about your clothing or the driver's speed on a call with their insurer.
