If you are stopped at a red traffic light in the left lane of a one-way street and the cross street is one-way from right to left, you may proceed to turn left onto the cross street once it is safe to do so. However, you must first come to a complete stop and yield to any oncoming traffic and pedestrians. Always check for any signs that may prohibit the turn on red.

When making a left turn at a traffic light without a green arrow, you should approach the intersection in the left lane and stop at the stop line. If the light is red, you must wait for the light to turn green unless there is a sign allowing a left turn on red from the one-way street. It is legal to enter the intersection to wait for a safe turn, provided you do not block oncoming traffic or cross over the stop line when the light is red. Always yield to oncoming traffic and pedestrians before completing your turn.

A red light flashing buoy indicates a navigational hazard or an area that requires caution for mariners. It typically marks the location of underwater obstacles, shallow waters, or other dangers. The flashing red light serves as a warning for boats to stay clear or navigate with care. These buoys are part of the maritime navigation system to help ensure safe passage for vessels.

Simulators are used to set traffic light timing by modeling traffic patterns, vehicle flow, and pedestrian behavior in a virtual environment. These simulations allow traffic engineers to analyze various scenarios and adjust light timings to optimize traffic efficiency, reduce congestion, and enhance safety. By testing different configurations and real-time data inputs, simulators provide insights into the best timing strategies before implementation in the real world. This approach minimizes disruptions and ensures that traffic signals are effectively tuned to the needs of the road network.

In Canada, traffic light durations can vary by municipality, but generally, the sequence includes green, yellow, and red lights. The green light typically lasts from 30 to 60 seconds, followed by a yellow light for about 3 to 5 seconds to warn drivers before the light turns red. The red light usually remains on for a similar duration as the green light, allowing for safe pedestrian crossing and traffic flow changes. Some intersections may also have variations to accommodate factors such as traffic volume and time of day.

A white traffic light is not commonly used in standard traffic control; however, in some contexts, it may signal the presence of emergency vehicles or specific traffic situations, such as guiding drivers in certain areas. In some regions, a white light can indicate a pedestrian crossing or a special event. Always refer to local traffic regulations for precise interpretations in your area.

If you see a flashing amber light near the entrance to a river lock, you should approach with caution and be prepared to stop. The flashing light typically indicates that the lock is in operation or that it is unsafe to enter. Always follow any additional signage or instructions, and wait until the light turns steady or you receive further guidance before proceeding.

When the traffic light turns green, the driver should first check for any pedestrians crossing the intersection and ensure that the road is clear of any obstacles. Once it's safe, the driver can proceed through the intersection, maintaining a cautious speed while being prepared for any unexpected actions from other drivers or pedestrians. Always follow traffic rules and signals to ensure safety for all road users.

A blinking red traffic light indicates that drivers must come to a complete stop before proceeding. It functions like a stop sign, requiring vehicles to yield to any oncoming traffic or pedestrians before continuing safely. After stopping, drivers may proceed when it is safe to do so.

Traffic lights play a crucial role in managing road safety and traffic flow, helping to prevent accidents and reduce congestion. By regulating the movement of vehicles and pedestrians at intersections, they promote orderly transit and enhance mobility in urban environments.
