There are a couple scenarios in this situation when a vehicle passes you on the left on a 2 lane highway. To answer your question, you should maintain your speed, but you can also slow down a little bit to get the passing vehicles past you faster.
If there's a danger of a head-on collision with an oncoming vehicle and the vehicle passing you, you need to pay attention to what the passing vehicle does, only one of two scenarios will occur:
If the passing vehicle decides to speed up to get past you to, you need to slow down!
If the passing vehicle slows down to drop back behind you, you need to speed up!
Whatever the passing vehicle decides to do in that scenario you do the opposite. The idea is to get the vehicle back into the right lane as quickly as possible!
the safe and legal passing of another vehicle requires that drive
So long as you are not speeding as you are passing yes. However if the vehicle you are passing is traveling at the speed limit the cop that books you will contend that you had no reason for passing.
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.
Exceeding the speed limit.
No. Even when passing, you're still bound by the speed limit of that road.
When another vehicle is passing you, you should maintain your speed and position in your lane to ensure stability and safety. Avoid making sudden movements or changes in direction, as this could create an unsafe situation. Additionally, keep a safe distance from the passing vehicle and be aware of any potential blind spots. Always use your mirrors to monitor the situation and signal appropriately if needed.
Common sense, decency.. that sort of thing. Legally... how it's categorised would depend on the state, but most would consider speeding up to prevent someone from passing to be aggressive driving.
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.
No. If the vehicle you are passing is going at the correct speed, why should you need to overtake. When overtaking a vehicle you should ensure there is enough clear road ahead of you to pass the vehicle without over speeding. If this is not the case you should not attempt an overtaking manoeuvre.
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.
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.
When passing another vehicle, the driver in the left lane has the right of way, provided they are legally allowed to do so. The driver being passed must maintain their speed and position without encroaching on the lane of the passing vehicle. Additionally, it’s essential for both drivers to follow local traffic laws and signals, which may dictate specific rules regarding passing. Always prioritize safety and ensure that the maneuver can be completed without endangering any road users.
