This law explains the right and left turning rules for drivers on highways. For right turns, drivers should stay close to the right-hand curb. On highways with three lanes, a driver in the middle lane can turn right into any suitable lane. Similarly, on one-way roads, a right turn should be made close to the right curb, finishing in any lane that's open for traffic in the turn direction. If there are special lanes marked for right turns, turns can be made from any of those lanes.

For left turns, drivers should keep close to the left edge of the leftmost lane. They need to enter and complete the turn only in a lane that is open for traffic in the turn's direction. On highways with three lanes ending at a two-way intersection, a driver in the center lane can turn left into any appropriate lane.

Drivers are not allowed to make a U-turn at intersections with traffic signals unless it's specifically allowed under certain conditions outlined in another section. Even then, the U-turn must be made from the far left lane that is authorized for traffic going in that direction. Similarly, at intersections with any traffic control devices, U-turns can only be made from the far left lane that legally allows travel in that direction.

The law allows the Department of Transportation and local authorities to put up signs or devices at intersections to control or ban turning movements. If you need to turn at an intersection, there will be a sign or marked lane to tell you what to do. Similarly, if turns are not allowed, signs will indicate this. It is illegal to ignore these signs or devices. Bicyclists are allowed to go straight through turn-only lanes if there's a sign permitting it, and the Department of Transportation is tasked with creating guidelines for marking these lanes.

If you're driving in a business district, you can only make a U-turn at an intersection or a specific spot on a divided highway where there's an opening. When making the U-turn, you should do it as close as possible to the left edge of your lane, especially if there are multiple lanes going in your direction.

If you're in a residential area, you can't make a U-turn if another vehicle is coming toward you from either direction within 200 feet. However, you can make a U-turn at an intersection if there's a traffic light or sign controlling the other vehicle.

This law makes it illegal to make a U-turn or use the driveway entrance or approaches to a fire station for turning around. You're not allowed to change direction in front of a fire station's driveway.

This law states that you cannot make a U-turn on a highway unless you can clearly see 200 feet in both directions and see any approaching traffic.

This law states that you cannot start or back up a vehicle on a highway unless you can do it safely. Before making these moves, ensure that they won't put you, other drivers, or pedestrians at risk.

Before changing lanes or turning, a driver must make sure it's safe and give the right signal if other vehicles might be impacted by their move.

Before you make a right or left turn, you must keep your turn signal on for the last 100 feet as you approach the turn.

If you're driving on a highway and need to stop or slow down quickly, you have to signal to the driver behind you first, as long as you have the chance to do so.

This law says that drivers must use signal lights to indicate their actions unless their vehicle doesn’t require them or isn't equipped with turn signals. If a vehicle doesn’t have turn signals, the driver must use hand and arm signals. Also, if your signal lights stop working while driving, you should use hand and arm signals too.

This law explains how drivers should signal their intentions by using hand and arm signals from the left side of their vehicle. If you want to make a left turn, extend your hand and arm horizontally. For a right turn, raise your hand and arm upward; however, bicyclists can extend their right hand and arm horizontally to the right. To indicate stopping or slowing down suddenly, extend your hand and arm downward.

This California law outlines the rules for school bus drivers when stopping to pick up or drop off students. Before reaching a bus stop, drivers must activate the amber warning lights 200 feet beforehand, and turn them off at the stop. The red lights and stop sign arm should be used whenever students are getting on or off, unless a traffic officer is present or in certain situations like snow or icy roads where it could be dangerous.

Drivers can only stop at designated school bus stops and must use the stop sign while helping young children (up to eighth grade) cross roads. Students need to cross in front of the bus, and the driver must ensure everyone is safe before moving the bus again. There are specific exceptions for using warning lights and stop signs, like breakdowns, certain road conditions, or particular locations. The California Highway Patrol can also mandate the use of warning systems for safety reasons.

This law allows local governments to pass rules that stop vehicles from making certain turns at intersections or between specific intersections.
