Quick Summary:
- Stop fully before turning right on red, unless a sign forbids.
- At four-way stops, follow arrival order and yield to the right.
- Never pass a school bus stopped with flashing red lights.
- Keep right on freeways, plan exits early, and follow mph signs.
Picking up a car hire in California can feel familiar, but a few everyday US road rules catch UK drivers out, especially at junctions and on multi-lane highways. The good news is that most of the stress comes from just five basics: right turn on red, four-way stops, school bus rules, reading speed signs, and lane discipline. Get these right and the rest of your trip becomes much calmer, whether you are threading through Los Angeles, crossing the Bay Area, or heading for coastal roads.
Before you set off, take two minutes in the car park to locate the handbrake, lights, wipers, and hazard button, plus how to adjust mirrors and seats. In the US you will be driving on the right, so your lane position is the opposite of home. A simple trick is to keep the centre line to your left and the kerb to your right. If your car hire includes a larger vehicle, such as an SUV, allow extra space at kerbs and drive-throughs, because lane widths and turning radii can feel different from the UK.
If you are collecting near Los Angeles International Airport, it helps to know that many freeways are fast, wide, and lane-heavy, and you may be mixing with drivers changing lanes frequently.

1) Right turn on red, treat it like a give way after a full stop
One of the most-missed US rules is that you can usually turn right at a red traffic light, but only after you come to a complete stop and check that it is safe. Think of it as stopping at a red light first, then treating the turn like a give way. If there is a sign saying “NO TURN ON RED”, you must wait for green. You will see this restriction more often in busy city centres, near schools, or at complex junctions.
Two details help UK drivers avoid awkward moments. First, you should stop before the white line or crosswalk. In California, pedestrians have strong priority, and stepping into the crosswalk is common. Second, if there is a right-turn lane controlled by a red arrow, treat it as no right on red unless signs clearly allow it. When in doubt, wait, US drivers may honk, but it is better than turning into conflict.
2) Four-way stops, read arrival order and be predictable
Four-way stops are everywhere in California neighbourhoods. Instead of traffic lights, each approach has a stop sign, and the rule is simple: the first vehicle to stop is the first to go. If two vehicles arrive at the same time, the vehicle on the right goes first. If you and another driver arrive opposite each other at the same time and both are going straight, you can proceed together. If one is turning left, they yield to the vehicle going straight.
What makes four-way stops stressful for UK visitors is hesitancy. Californians tend to expect confident, rule-based movement. Do a full stop, make quick eye contact where possible, and go when it is your turn. Do not wave others through in a way that changes the order, because it can create confusion. Also remember that cyclists may be treated as vehicles here and might take their turn at the stop sign, even if they roll through slowly.
3) School buses, do not pass when red lights flash
California takes school bus safety seriously. If a school bus is stopped with flashing red lights and a stop arm extended, you must stop and you must not pass. This applies even if you are behind the bus and even if you are coming from the opposite direction on an undivided road. Stay stopped until the red lights stop flashing and the bus moves again.
On roads with a physical central divider or a raised median, traffic on the opposite side may be allowed to continue, but do not rely on assumptions. If you are unsure, stop. Fines can be steep, and it is one of the easiest mistakes for visitors to make because it feels different from typical UK school transport rules.
4) Speed signs and units, think in mph and watch “when posted” limits
Speed limits are in miles per hour, but because UK drivers think in mph too, the bigger adjustment is how often limits change and how they are enforced. Urban arterials might be 35 mph, residential streets 25 mph, and freeways often 65 mph, with some stretches higher or lower. Do not assume the limit from the road feel, read the signs, and remember that traffic flow may be above the posted limit.
Look out for signs that add conditions such as “WHEN CHILDREN ARE PRESENT” or “WHEN FLASHING”. In California, keep an eye on construction zones where temporary limits can be enforced aggressively. If your car hire has cruise control, it can reduce mental load on long freeway stretches, but always disengage when traffic gets dense.
5) Lane discipline on freeways, keep right and plan exits early
California freeways can be wide, fast, and busy, and lane discipline is a common source of stress for UK visitors. The general expectation is slower traffic keeps right, faster traffic uses the left lanes to overtake, and you should not sit in the far-left lane unless you are passing. Although you will see plenty of exceptions, staying right makes you more predictable and reduces pressure from faster drivers behind.
Exits can appear quickly and may be on the right, with several lanes feeding different destinations. Start reading signs early, because they often list multiple road names and city directions. If you miss an exit, keep going and take the next one. Cutting across several lanes at the last second is risky and will annoy other drivers.
HOV and carpool lanes are common, especially around Los Angeles and San Diego. They are usually the far-left lanes marked with a diamond symbol, and they may have time-of-day restrictions and passenger requirements. Do not enter a separated carpool lane across double solid lines. If you are not sure you qualify, stay out, fines can be significant. If your trip starts in San Diego, pages like car hire San Diego SAN and National car rental San Diego SAN can help you orient around airport pickups and local driving.
FAQ
Can I always turn right on a red light in California? No. You can usually turn right on red after a full stop and yielding, but you must obey “NO TURN ON RED” signs and any red arrows that prohibit the turn.
Who goes first at a four-way stop? The first vehicle to come to a complete stop goes first. If vehicles arrive together, yield to the vehicle on your right, and be predictable.
What should I do if a school bus stops with flashing red lights? Stop and do not pass in either direction on undivided roads. Wait until the red lights stop flashing and the bus moves again.
Are speed limits in California strictly enforced? They can be, especially in construction zones and school areas. Follow posted mph signs rather than copying the fastest traffic flow.
Which lane should I use on California freeways? Keep right unless overtaking. Plan early for exits, avoid last-second lane sweeps, and only use HOV lanes if you meet the posted rules.
