Quick Summary:
- You can often turn right on red after stopping, unless signed.
- Make complete stops at every stop sign, then go by arrival order.
- Keep right unless passing, and avoid weaving across fast multi lane roads.
- Speed limits are in mph, so leave space and drive smoothly.
Collecting a car hire in California feels familiar at first, wide roads, clear signs, and lots of space. The surprises tend to come from small rule differences and local driving habits, especially around junctions, lane use, and how strictly certain signs are enforced. If you have driven in the UK for years, you already have the hazard awareness you need. What helps most is knowing which habits to change before you leave the car park.
California rules are set at state level, but you will also see local restrictions posted on signs. Always follow the sign in front of you, especially around schools, roadworks, and downtown one way systems. If your pick up is at a major airport, these tips apply immediately from the first exit ramp. You can see typical collection set ups for car hire at San Francisco Airport or car rental at Los Angeles LAX, where you join fast moving multi lane roads quickly.
Driving side, controls, and first five minutes
Like the UK, you drive on the right in California, but because the steering wheel is on the left, most UK visitors adapt quickly. The main early risk is drifting towards the centre line on narrower roads, or turning into the wrong lane on quieter streets. When you turn, aim for the nearest legal lane on the right hand side of the road you are entering.
Before you move off, take 30 seconds to set mirrors, lights, and sat nav. In many US cars, the indicator and wiper stalks may be swapped from what you are used to. If you are hiring a larger vehicle, such as an SUV for family luggage, factor in the blind spots and longer stopping distance. Hola options like SUV rental in San Francisco can be a good fit for road trips, but do a slow lap of the car park to get comfortable.
Right turn on red, when it is allowed and when it is not
The biggest rule difference UK drivers ask about is the right turn on red. In California, you may usually turn right at a red traffic light after coming to a complete stop, checking for pedestrians and cyclists, and giving way to cross traffic. It is similar to a permitted left on red in parts of the UK, but much more common and expected in the US.
There are important exceptions. If you see a sign saying No Turn On Red, you must wait for green. You also must not turn if it would cut across a pedestrian crossing with people stepping off, or if visibility is poor. Treat it as a cautious option, not an obligation, and do not feel pressured by a horn. When in doubt, wait for green and proceed legally.
Stop signs, full stops, and four way stops
Stop signs are used far more than in the UK, including at quiet residential junctions. The rule is simple but enforced: stop fully, with the wheels stopped, before the stop line or crosswalk. Rolling stops are a common reason visitors get pulled over.
At a four way stop, each approach has a stop sign. The right of way is based on arrival order. The first vehicle to stop goes first. If two arrive at the same time, the vehicle on the right goes first. If you and an oncoming vehicle arrive together and both want to go straight, you can proceed together. If one is turning left, it yields to the oncoming straight mover unless the arrival order clearly gives it priority. Make your intentions obvious with early indicators and steady movement once you go.
Lane discipline, passing, and multi lane freeways
On freeways, you will notice a strong keep right except to pass culture in theory, but in busy city traffic people may pass on either side. As a visitor, take the calm approach: stay in the lane you need for your next junction, keep a safe following distance, and avoid last second weaving.
Overtaking can happen on the right, which may feel uncomfortable. Check mirrors frequently, signal early, and make lane changes smoothly. If you are slower than the flow, move right when safe. If you are in the far left lane, expect faster drivers to appear quickly behind you, and do not try to police speeds. Move right when you can.
Speed limits, mph, and matching the flow safely
California speed limits are in miles per hour. That sounds obvious, but it matters when you glance down and see 65 on the sign. Typical freeway limits are 65 to 70 mph, with lower limits in urban stretches. Surface streets are often 25 to 45 mph. Speed cameras are less common than in parts of the UK, but highway patrol enforcement is real, and stopping distances at US speeds can catch visitors out.
A practical rule is to drive at the posted limit unless conditions require less. You will hear people say to match the flow of traffic. In practice, do not exceed a limit just because others do. Instead, keep right, leave a bigger gap than you would in the UK, and let faster traffic go around you.
School buses, pedestrians, and common enforcement
School bus rules are strict. If a school bus has flashing red lights and a stop arm out, you must stop. On many roads, traffic in both directions must stop. Divided highways can differ, but do not guess. If you are unsure, stop and wait until the lights stop flashing and the bus moves.
California is strict on handheld phone use. Use hands free if you must, and ideally set directions before moving. Everyone should wear a seat belt, front and back. If you are travelling with children, check booster and child seat requirements that apply to their age and height.
If your trip starts in Silicon Valley or the South Bay, planning your first route in advance helps, especially if you are collecting from Hertz car rental in San Jose and heading straight onto multi lane highways.
