Speed, Lane Use, Turns, and Parking
Key Takeaways
- California's Basic Speed Law means the posted limit is not always safe; traffic, weather, surface, visibility, pedestrians, and bicyclists can require a lower speed.
- Default California speeds include 65 mph on most highways, 55 mph on two-lane undivided highways and when towing, 25 mph in business or residential districts, and 15 mph at blind intersections and alleys.
- Use turn signals before turns and lane changes, check blind spots, and enter bike lanes only when legally allowed, such as within 200 feet of a right turn.
- Right turns on red require a complete stop, no posted ban, and yielding; left on red is limited to one-way street onto one-way street unless prohibited.
- Curb colors are testable: red no stopping, yellow loading, white passenger pickup/dropoff, green limited time, and blue disabled parking.
Speed, Lane Use, Turns, and Parking
California speed and lane questions are usually scenario questions. The posted number matters, but the first rule is the Basic Speed Law: never drive faster than is safe for current conditions. Rain, fog, rough pavement, congestion, pedestrians, bicyclists, road work, and visibility can all make the legal speed lower than the posted limit.
Speed Defaults to Memorize
| Location or condition | Default California speed rule unless posted otherwise |
|---|---|
| Most California highways | 65 mph ideal maximum |
| Two-lane undivided highway | 55 mph |
| Vehicle towing a trailer | 55 mph |
| Business or residential district | 25 mph |
| Within 500 feet of a school while children are outside or crossing | 25 mph, with some school zones posted as low as 15 mph |
| Blind intersection with blocked view and no stop signs | 15 mph |
| Alley | 15 mph |
| Certain railroad crossings with limited visibility | 15 mph within 100 feet when tracks cannot be seen for 400 feet both ways, unless controlled by gates, warning signal, or flag person |
If a question says conditions are poor, reduce speed even if the choice listing the posted limit looks familiar. If a question says you are slower than normal traffic, use the right lane when practical and do not block normal flow.
Lane Use and Bike Lanes
Use the right lane to enter or exit traffic and the left lane to pass or turn left when lanes are available. Before a lane change, signal, check mirrors, and turn your head to check the blind spot. On a freeway, DMV expects a signal at least five seconds before changing lanes or exiting.
Bike lanes are for bicyclists. A driver may enter one only for limited reasons, such as parking where allowed, entering or leaving the road, or turning within 200 feet of an intersection. Before entering a bike lane for a right turn, check over your shoulder and merge behind any bicyclist rather than cutting across their path. When passing a bicyclist, give at least three feet if you cannot change lanes; if three feet is not available, wait.
Turns and Red-Light Caveats
For a right turn, move close to the right edge or enter the right-turn lane at the opening, signal about 100 feet before the turn, check for pedestrians, bicyclists, and motorcycles near the curb, then complete the turn into the right lane without swinging wide.
| Turn situation | California rule |
|---|---|
| Right on steady red | Allowed only after a complete stop, unless a No Turn on Red sign prohibits it, and only after yielding. |
| Right on red arrow | Not allowed; wait for green. |
| Left on steady red | Allowed only from a one-way street onto another one-way street, unless a sign prohibits it. Yield to vehicles, pedestrians, and bicyclists with the green. |
| U-turn | Use the left-turn lane or far-left lane; never make it where posted No U-turn, at railroad crossings, on one-way streets, or where you cannot see 200 feet each way. |
| Center left-turn lane | Enter within 200 feet of the turn and use it only for left turns or U-turns, not passing. |
Parking and Curb Colors
Colored curbs are quick-recall items:
| Curb color | Meaning |
|---|---|
| Red | No stopping, standing, or parking, except buses at bus-only red zones |
| Yellow | Load or unload passengers and freight; obey posted time limits |
| White | Stop only long enough to pick up or drop off passengers |
| Green | Park for a limited time shown by signs or curb markings |
| Blue | Disabled parking only with a valid placard or plate |
For hill parking, set the parking brake. Downhill means wheels toward the curb; uphill with a curb means wheels away from the curb; no curb means wheels to the right. The exam pattern is consistent: choose the position that keeps the vehicle from rolling into traffic.
You are on a residential street posted at 25 mph, but heavy rain is limiting visibility and pedestrians are near parked cars. Which answer best applies California's speed rule?
You want to turn right at the next intersection, and a bike lane runs beside your lane. What is the correct approach?
