According to the California “Basic Speed Law” you may never drive faster than is safe for current conditions. For example, if you are driving 45 mph in a 55 mph speed zone during a dense fog, you may be cited for driving “too fast for conditions”.
Important: Regardless of the imposed speed limit on the relevant road section, your speed should depend on:
• the number and speed of other vehicles on the road
• whether the road surface is smooth, rough, graveled, wet, dry, wide, or narrow
• bicyclists or pedestrians on or crossing the roadway
• whether it is raining, foggy, snowing, windy, or dusty
Highway maximum speed limit
The maximum speed limit on the most California highways is 65 mph. You may drive 70 mph where posted.
Unless otherwise posted, the maximum speed limit is 55 mph on a two-lane undivided highway and for vehicles towing trailers.
Other speed limit signs are posted for the type of roads and traffic in each area.
In case of construction zones on the road, usually there are reduced speed zones.
Heavy Traffic or Bad Weather
In this case you must drive slower when there is heavy traffic or bad weather. However, if you block the normal traffic speed and reasonable movement of traffic by driving too slowly, you may be fined. If you choose to drive slower than other traffic, do not drive in the “Number One Lane” (fast lane).
In case the another driver is close behind you and wishes to drive faster, you should move to the right and give him/her a way.
Towing Vehicles, Buses, or Large Trucks
When you tow a vehicle or trailer, or drive a bus or 3 or more axle truck, you must drive in the right most lane or in a lane specially marked for slower vehicles. If there are no lanes are marked and there are four road lanes (or more) in your direction, you may only
drive in either of the two lanes closest to the right edge of the road.
Blind Intersections
The speed limit for a blind intersection is 15 mph.
A “blind” intersection is if there are no stop signs at any corner and you cannot see for 100 feet in either direction during the last 100 feet before crossing. Trees, bushes, buildings, or parked cars at intersections can block your view to the side. If your view is blocked, move slowly forward until you can see.
Alleys
The speed limit in any alley is 15 mph.
Near Railroad Tracks
The speed limit is 15 mph within 100 feet of a railroad crossing where you cannot see the tracks for 400 feet in both directions. You may drive faster than 15 mph if the crossing is controlled by gates, a warning signal, or a flag man.
Always drive slowly and carefully near schools, playgrounds, parks, and residential areas.
When driving near to a school while children are outside or
crossing the street, the speed limit is 25 mph unless otherwise is posted.
If the school grounds have no fence and children are outside, never drive faster than 25 mph.
There are some school zones with speed limits as low as 15 mph.
When you are driving near school you must take attentions to:
• bicyclists and pedestrians.
• school safety patrols or crossing guards.
• stopped school buses and children crossing the street.
Some school buses flash yellow lights when preparing to stop. The yellow flashing lights warn you to slow down and prepare to stop.
When the bus flashes red lights (located at the top front and back of the bus), you must stop from either direction until the children are safely across the street and the lights stop flashing.
You are obliged to remain stopped as long as the red lights are flashing. If you fail to stop, you may be fined up to $1,000 and your driving license could be suspended for 1 year.
If the school bus is on the other side of a divided or multilane highway (two or more lanes in each direction), you do not
need to stop.
When passing pedestrians or bicyclists you must slow down and pass safely, and pass only at a safe distance (typically 3 feet or more for bicyclists).
Railway tracks crossing rules
When approaching a railway crossing you must look in both directions and listen for trains. Many crossings have multiple tracks and you must stop before crossing, if necessary. Cross railroad tracks
only at designated crossings and only when it is safe to do so.
Flashing red traffic light signal means "STOP!". You must Stop at least 15 feet before the first track, but no more than 50 feet, from the nearest track when the crossing devices are active or a person warns you a train is coming.
In California the traffic lanes are often referred to by number.
The left or “fast” lane is the “Number 1 Lane.”
The lane to the right of the “Number 1 Lane” is the “Number
2 Lane,” then the “Number 3 Lane,” etc.
You must drive in the lane with the smoothest flow of traffic.
If there are three road lanes in one direction, pick the middle lane for the smoothest driving.
For faster driving, bypassing, or turning left, the left road lane must be used.
For slow driving, entering or turning off the road, use the right lane.
If there are only two road lanes in your direction, pick the right lane for the smoothest driving.
Carpool/High-Occupancy Vehicles (HOV) Lanes
An HOV lane is a special lane used only for carpools, buses, motorcycles, or low-emission vehicles.
Signs at the on-ramp or along the freeway tell you the minimum
number of people per vehicle required for the carpool/HOV lane(s).
These signs also list the days of the week and the hours when the
carpool/HOV requirement applies. The pavement in this lane is
marked with a diamond symbol and the words “Carpool Lane.” These
lanes are also known as HOV lanes. Do not cross over double parallel
solid lines to enter or exit any carpool/HOV lane except at designated entry or exit places.
The general road markings in California are in yellow and white:
- Solid yellow line - means "No passing if solid yellow line is on your side".
- Double solid lines means "DO NOT pass".
- Broken yellow line means "May pass if movement can be made safely."
- Double solid white lines indicate a lane barrier between a regular use and a preferential use road lane, such as a carpool/HOV. Never change road lanes designed by this marking. Wait until a single broken white line appears.
Never drive to the left of the Two solid yellow lines unless you are:
- in a carpool lane/high occupancy vehicle (HOV) lane that has a designated entrance on the left.
- there is road signs indicating you must drive on the other side of the road.
The major public roads in California are free, but tolls are charged on some roads and bridges.
It's good to carry USD currency to pay toll for the toll bridges that do not accept credit cards but do accept cash.
Since 2016, the following toll roads are fully automated and do not accept cash payments:
San Francisco Bay Area: Golden Gate Bridge (south-bound)
Southern California: SR 73, 133, 241 & 261 (Orange County), SR 125 (San Diego County - exact change or credit card OK)
The visitors paid the toll in cash can use the most California highways without worrying about fees or fines except for the specific automated toll roads. Visitors who do not have a FasTrak account should avoid using the "FasTrak Only" road lanes and use the "Cash", "Fastrak/Cash combo lanes" or unmarked lanes instead.
FasTrak is the transponder that is used to pay automated tolls in California. There are:
- Standard version, basically just a white square shaped device.
- FasTrak "Flex" (Bay Area) or /Metro Express Lanes (Southern California) version, which looks the same as the standard except for a switch to indicate the number of people in the car. (1, 2 or 3+)
Golden Gate Bridge - toll rate
The fee is $2.50 per axle.
