Short answer is because human eyes don't respond well to the color red, so it's a very poor color choice for illumination purposes. Longer answer is the whole idea of having lights at night is to be able to see things at night. Human eyes are more sensitive to green and yellow, less sensitive to blue and red.
From the California Driver Handbook: Solid Red– A red signal light means “STOP.” You can make a right turn against a red light after you stop then yield to pedestrians, bicyclists, and vehicles close enough to be a hazard. Make the right turn only when it is safe.
If two or more drivers come to a stop at the same time, they yield to the driver on their right. But if you're making a left-hand turn, you're expected to yield to any vehicle that's facing you and coming across the intersection – even if you had to wait for traffic to clear and that driver got there after you did.
You may turn left on a red light from a one-way street onto another one-way street or from a two-way street onto a one-way street. Treat as you would a right turn on a red light. You must completely stop and yield to others before proceeding.
A red arrow means traffic waiting to turn must wait behind the stop line until the arrow turns green or disappears, even if there is no traffic on the road. You must not go straight ahead or turn left. You may turn right. You must not turn right but you can go straight ahead or turn left if the way is clear.
U-Turn Right of Way Laws
The answer depends on the situation. If you are at an intersection that allows a U-turn and you have the green arrow light, then you are the one with the legal right-of-way. On the other hand, a driver making a U-turn on a red light must yield to oncoming traffic.When you make a right turn from any of the multiple right turn lanes, you will need to stay in your lane using white dash lines as your guide of staying in your lane. You must STOP until the light turns green. You can GO, but you must still YIELD to vehicles, pedestrians or bicycles that are in your path.
How It Works: Right-of-Way
- when you're at a yield sign.
- to pedestrians in a crosswalk.
- to another vehicle already in an uncontrolled intersection (one that doesn't have any traffic lights or signs)
- and when making left-hand turns, you must yield to oncoming traffic or pedestrians.

At what speed should you make a turn? This will depend on a number of factors, such as the angle of the turn. Most drivers would say that you should make a right turn when at 15 kilometers per hour and 20 kilometers per hour when you have to turn to the left.
Before you do anything you must obey the red light and come to a complete stop in the rightmost lane with your turn signal on. Make sure you stop behind the limit line (or crosswalk or intersection if there is no line). There's no need to roll the stop and end up with a ticket or cause a collision.
Roeske says that cases in which traffic lights don't eventually change are rare. But if a light does not turn green after an unreasonable amount of time and a motorist takes an illegal course of action, the driver can be cited.
Right turns on red are permitted in many regions of North America. All 50 states, the District of Columbia, Guam, and Puerto Rico have allowed right turns on red since 1980, except where prohibited by a sign or where right turns are controlled by dedicated traffic lights.
Welcome to West Milford, home of the country's longest traffic light. Drivers pulling up to the light at the intersection of Clinton Avenue and Route 23 in Passaic County can wait as long as 5 minutes and 33 seconds during the morning rush hour if they approach it as it is turning red.
Red light cameras generally don't scan people turning right because in most places “right on red” is legal. However, red light cameras don't usually fine people who overrun the line and don't actually go through the light.
Eric Roeske of the State Patrol, the driver must stay stopped at the red light. Roeske says that cases in which traffic lights don't eventually change are rare. But if a light does not turn green after an unreasonable amount of time and a motorist takes an illegal course of action, the driver can be cited.
There is no 3 seconds rule. When stopping at a stop sign or stop line you need to come to a complete stop at or before the stop line (or intersection if there is no stop line), look and then give way to vehicles and/or pedestrians. Once it is safe, proceed.
While we're on the topic, there is one last part to the parking law that states that it's “unlawful for any person to reserve or attempt to reserve any portion of a highway for the purpose of stopping, standing, or parking ” This is the “no saving spots” law.
To turn right on a red light, start by getting into the right-hand lane if there are multiple lanes. Slow down as you approach the red light and come to a complete stop when you reach the crosswalk. Check for oncoming traffic and pedestrians. Wait until your path is clear and then make the right turn.
You look: Over your right shoulder while backing. Toward other vehicles, bicyclists, and pedestrians when necessary.
When you're making a left-hand turn, you should always give the right-of-way to drivers who don't have stop signs or yield signs. If you're turning left at a green light, pull out into the intersection but wait to turn left until all oncoming traffic has passed.
Traffic check
- You observe traffic (vehicles, bicyclists, and pedestrians):
- You check the blind spot by looking over your right or left shoulder before merging into the bike lane or center left turn lane.
- You look toward other vehicles, bicyclists, and pedestrians when necessary.
- You react safely to traffic situations.
As people have pointed out, flashing red and blue lights in your rearview mirror are the most obvious clue. However, if you trip the sensors of a red light camera, you won't know until you get the notice of infraction in the mail if you run a red light during the day. At night, you may see the flash from the camera.
