Driving In The USA and Canada - On Ramp Metering

In large cities some on ramps (entrance slip roads) to busy freeways have on ramp metering. A traffic light admits one (or sometimes two) vehicles at a time during peak traffic times.

The road sign "One vehicle per green" indicates that only one vehicle must pass the traffic light each time it turns to green.

The road sign "Ramp Signal On" is lit when metering is active. This sign will be located along the on ramp before the actual metering traffic light.
