Speed LIMIT means exactly that. That is the fastest speed you are allowed to travel under perfect road conditions. No state allows you to exceed the speed limit to pass another vehicle.
No, it is not legal to pass another vehicle by going over the speed limit.
The speed limit is exactly that - the speed limit. While a reasonable excess of speed might be overlooked when overtaking another vehicle, there is no guarantee. You can be pulled over and cited for speeding, still.
In practice, It is acceptable to increase the speed of your vehicle over the legal speed limit to pass or overtake another vehicle. Legally, it is not permitted. If the other vehicle is already at the speed limit, you should not be passing it. If it were a police car you were passing, at any speed above the speed limit, they could stop you.
the safe and legal passing of another vehicle requires that drive
Yes it is acceptable to momentarily accelerate over the speed limit tp get around a vehicle moving slower than the posted speed limit but you must return to the speed limit after passing.
Exceeding the speed limit.
The speed limit is applicable when overtaking another vehicle, just as it is at any other time. A police officer observing you overtaking another vehicle MIGHT decide what you did was within reason, and not bother you, but they have full authority to pull you over for exceeding the speed limit- even when overtaking a slower moving vehicle- should they decide to.
No. Even when passing, you're still bound by the speed limit of that road.
Do not exceed the speed limit is correct
In practice, It is acceptable to increase the speed of your vehicle over the legal speed limit to pass or overtake another vehicle. Legally, it is not permitted. If the other vehicle is already at the speed limit, you should not be passing it. If it were a police car you were passing, at any speed above the speed limit, they could stop you.
The speed limit is 55mph.
The speed limit is exactly that - the speed limit. It remains in place even when overtaking another vehicle. Chances are, if you're going five over the speed limit to overtake a vehicle, and a police officer observes it, they'll let it slide. Do 20 over, and they're not going to. However, there is no guarantee - the moment you go over the speed limit, you're subject to be cited for it, even in a passing situation.
