Traffic Signals
Traffic signals control the right of way and provide for a smooth, orderly flow of traffic. If a signal appears dark, such as during a power failure, you should stop as if there are stop signs in all directions. When a traffic signal is out of order and flashes yellow or red, you must obey that signal as defined below.

Steady Circular Red
A steady red signal means stop and remain stopped until the signal changes. You are allowed to make the following turns on red after coming to a complete stop unless a sign or police officer states otherwise. When entering a two-way road, you may turn right. When entering a one-way road, you may turn right or left in the direction of the one-way road.

Ramp Meter
Ramp meters are placed on some freeway on-ramps. These look like traffic signals, but only operate during certain times of the day. For multi-lane on-ramps, each lane has a ramp meter. Only one vehicle can proceed each time the green light comes on. When your light turns green, speed up to merge with traffic on the freeway. Ramp meters will appear dark when not in use. Do not stop at a dark ramp meter.
