Traffic Control Signals

• Traffic control signals guide, warn, and regulate traffic flow for all road users.

Traffic Light Colors

• Flashing Yellow: Caution required; slow down and be alert.

Turning Regulations

• A right turn on red is allowed only after a complete stop and yielding to all pedestrians and vehicles.
• A left turn on red is permissible from a one-way to another one-way street, provided there is no prohibition.

Intersection Protocol

• Approaching a red light requires a complete stop; wait for cross traffic before turning.
• For flashing red lights with no other vehicles, stop and navigate safely.

Green Lights

• Green Light: Indicates to go, but yield to any road users in the intersection first.
