A steady yellow light means that vehicles must stop under the same conditions as if it were a steady red light, unless when it comes on, the vehicle is so close to the stopping point that it cannot stop before it under sufficient safety conditions.
If the yellow light or lights are alternately flashing, they require drivers to exercise extreme caution and, where appropriate, give way. In addition, they do not exempt from compliance with other signs requiring a stop.
