California speed limits default to 65 mph on multilane highways, 55 mph on two-lane undivided roads, 25 mph in residential and business districts, and 15 mph in alleys and at blind intersections, with lower posted limits in school and senior zones. On top of those numbers, the Basic Speed Law lets an officer cite you for driving too fast for conditions even when you’re under the sign. A standard speeding ticket runs from $234 to $486 once penalty assessments are added, plus one point on your DMV record.
Default Limits When No Sign Is Posted
California fills the gap with statutory limits based on road type, and these apply automatically whether or not a sign is up:
- Multilane highways: 65 mph. Some freeway segments are posted at 70 where Caltrans has authorized it, but 65 is the baseline.
- Two-lane undivided highways: 55 mph, unless a higher speed has been posted after an engineering and traffic survey.
- Residential and business districts: 25 mph.
- Alleys: 15 mph.
The 65 and 55 mph highway limits come from Vehicle Code Section 22349.1California Legislative Information. California Vehicle Code 22349 A city doesn’t need to sign every residential street for the 25 mph limit to apply.
The Basic Speed Law
The most important rule on any California road isn’t a number. Vehicle Code Section 22350 says you can never drive faster than what’s reasonable and safe given the actual conditions, regardless of the posted limit. Weather, visibility, traffic, and the width and condition of the road all factor in. If fog cuts visibility to 50 feet and you’re doing 60 in a 65 zone, you can still be cited.
The Basic Speed Law runs alongside the posted limit, not instead of it. You have to obey both, and whichever produces the lower safe speed is the one that governs. That’s why tickets get written for speeds well under the sign during storms and heavy traffic.
Reduced-Limit Zones
School Zones
The limit drops to 25 mph on roads near school grounds when children are present. Local authorities can also establish time-restricted school zones covering school hours, recess, and before- and after-school periods, and those limits apply during the posted times even if no children are visible.2California Legislative Information. California Vehicle Code 22352 School zone violations can carry enhanced consequences.
Senior Zones
Cities can designate 25 mph senior zones on streets near senior centers or facilities primarily used by older adults when signs are posted. Senior zones don’t require an engineering and traffic survey, which makes them easier for local agencies to establish than most reduced-limit zones.3California Legislative Information. California Vehicle Code 22358.4
Blind Intersections
If you can’t see cross traffic from at least 100 feet away during the last 100 feet of your approach, the limit drops to 15 mph. This catches drivers off guard in older neighborhoods with tall hedges or walls at the corner. The rule doesn’t apply at intersections controlled by stop signs, yield signs, or traffic signals.2California Legislative Information. California Vehicle Code 22352
Railroad Crossings
A 15 mph limit also applies at railroad crossings where your view is obstructed. Specifically, if in the last 100 feet before the crossing you can’t see clearly for 400 feet in both directions along the tracks, slow to 15 mph. The rule doesn’t apply where a signal device or flagperson is present.2California Legislative Information. California Vehicle Code 22352
Construction and Maintenance Zones
Certain highway work areas are designated as Safety Enhancement-Double Fine Zones. Speeding in one bumps the ticket up to the next penalty tier on the uniform fine schedule, so a 1–15 mph violation is charged as if it were 16–25 mph over. The enhancement applies whenever proper signs are posted, even if no workers are on site.4California Legislative Information. California Vehicle Code 42010
Lower Caps for Trucks and Towing
Some vehicles face a hard 55 mph ceiling on every California highway, regardless of the posted limit. Under Vehicle Code Section 22406, the cap applies to trucks or truck tractors with three or more axles, any truck towing another vehicle, passenger vehicles or buses towing another vehicle, school buses carrying students, farm labor vehicles carrying passengers, vehicles transporting explosives, and trailer buses.5California Legislative Information. California Vehicle Code 22406
Tank vehicles hauling more than 500 gallons of flammable liquid face steeper penalties: at least $500 for a first offense, and at least $2,000 plus a possible six-month suspension of hazmat endorsements for a repeat offense within two years.
Lane rules follow the speed cap. Where signs designate specific lanes, those are the only ones available. Where no lane signs are posted, these vehicles must stay in the far-right lane or as close to the right edge as practical, and on a divided highway with four or more lanes in the same direction they may also use the lane immediately left of the right-hand lane.6Caltrans.

What a Speeding Ticket Costs
Base fines look modest. The real bill doesn’t, because state and county penalty assessments, court operations charges, and a conviction assessment stack on top. The 2025 Uniform Bail and Penalty Schedule sets these totals for a standard speeding infraction:
- 1–15 mph over: $35 base, $234 total
- 16–25 mph over: $70 base, $363 total
- 26 or more mph over: $100 base, $486 total
In a Safety Enhancement-Double Fine Zone the ticket moves up a tier, so a 1–15 mph violation costs $363 instead of $234.7California Courts. Uniform Bail and Penalty Schedules – 2025 Edition4California Legislative Information. California Vehicle Code 42010
Driving Over 100 MPH
Triple digits fall under Vehicle Code Section 22348(b), with its own escalating penalty structure:
- First conviction: Base fine up to $500. The court may suspend your license for up to 30 days.
- Second conviction within three years: Base fine up to $750. Six-month license suspension is mandatory.
- Third conviction within five years: Base fine up to $1,000 and a mandatory one-year license suspension.
Those fine amounts are base figures before penalty assessments, so the actual bill runs several times higher.8California Legislative Information. California Vehicle Code 22348 The shift from “may suspend” on the first offense to “shall suspend” on the second is where this becomes serious. A first ticket at 100+ mph might not cost you your license. A second one within three years will.
Points, Traffic School, and Your License
Every speeding conviction adds one point to your DMV record. Commercial vehicle violations carry 1.5 points.9California State Department of Motor Vehicles. Driver Negligence Points feed into California’s Negligent Operator Treatment System, and the DMV starts intervening at these thresholds:
- 4 or more points in 12 months
- 6 or more points in 24 months
- 8 or more points in 36 months
Reach any of those on a standard Class C license and you’ll get a warning letter, followed by potential suspension or revocation if the pattern continues.9California State Department of Motor Vehicles. Driver Negligence
Traffic school is the main way to keep a point off your record. If you have a valid noncommercial license and haven’t attended in the last 18 months, you can usually request the option from the court. Complete an approved course and the point won’t appear on your DMV record, which also keeps it out of view of your insurance company.10California Courts | Self Help Guide. Traffic School Tickets involving alcohol, drugs, or equipment violations don’t qualify. You still pay the full fine plus a court processing fee and the school’s registration fee, but avoiding an insurance rate hike usually makes the math work in your favor.
