No, you legally should NOT move until the flashers stop and if there is a stop sign on the bus that it has been retracted. It doesn't matter if a bus driver flags you to go... or signals you to go. If those flashers are red or orange---keep your foot solidly on the brake. Go when the flashers and stop-sign end, AND you can see no other dangers, like a kid in the roadway.
When a yellow light is flashing at an intersection, a driver must proceed with caution and be prepared to stop if necessary.
When approaching an intersection with a flashing yellow light, a driver must proceed with caution and be prepared to yield to oncoming traffic or pedestrians.
When approaching a flashing yellow arrow traffic light, a driver should proceed with caution and yield to oncoming traffic before making a left turn.
When encountering a flashing red light at an intersection, a driver must come to a complete stop, yield the right of way to any other vehicles or pedestrians, and proceed only when it is safe to do so.
If the traffic signals are not working, drivers should treat the intersection as a four-way stop. This means that each driver should come to a complete stop and then proceed in the order they arrived at the intersection. It is important to proceed with caution and yield to other vehicles as needed.
In Ohio, the driver of any vehicle approaching a school bus stopped in order to pick up or leave off a child, must halt at least ten feet behind or in front of the school bus. The driver must not proceed until the school bus moves forward or the school bus driver signals the driver to go ahead. A driver who violates Ohio traffic laws concerning stopping for school bus may be fined up to $500.
If there are pedestrians still crossing when the amber light is flashing, the motorist must remain stationary. If there are no pedestrians crossing, the motorist can proceed. (But, be careful of pedestrians taking a chance and attempting to cross when the amber light is flashing - it is best to use caution until the light turns green.)
If one turn signal is flashing fast it is to warn the driver they need to replaced either the front or back signal bulb.
That would be the other driver's fault, unless you were stopped somewhere that there was no reason to stop. If you have your emergency signals on, however, then it would be the other driver's fault regardless.
When encountering flashing red lights, a driver should always stop.
A driver is required to take a mandatory stop at stop signs, traffic signals displaying a red light, and certain intersections or pedestrian crossings where indicated by signage. This ensures the safety of all road users and allows for proper assessment of the traffic conditions. After stopping, the driver may proceed when it is safe to do so, ensuring the way is clear of pedestrians and other vehicles.
Yield signs are red and white with red letters. These signs alert the driver to any upcoming hazards or road conditions that do not reflect an Immediate condition. A yield sign calls on the driver to do the following: Slow down, defer to oncoming or intersecting traffic, stop when necessary, proceed when safe, and remain aware of oncoming vehicles. A flashing yellow light has the same meaning as a yield sign. When a flashing yellow light is observed, the driver should be cautious both prior to and while passing through the intersection.
