Final answer:
No, drivers are not allowed to exceed the speed limit to pass another vehicle, even by a margin of 10 MPH or less, as speed limits are the maximum legal speeds under ideal conditions.
Step-by-step explanation:
Drivers are not allowed to exceed the speed limit when passing other vehicles. Traffic laws are clear that the speed limits posted are the maximum legal speed under ideal conditions. This means if the speed limit is 30 miles per hour, going 31 miles per hour technically puts you over the limit. While there may be some leeway in enforcement, this is not an allowance to break the law but rather an acknowledgment of speedometer imprecision and minor discrepancies.
Aggressive behaviors like tailgating and honking to pressure another driver to speed up, as in the case of Peter, are not only legally questionable but potentially unsafe. It's also important to note that conditions such as driving in a business district could demand lower speeds for safety. In conclusion, exceeding the speed limit to pass is not legally justifiable, not even by 10 MPH or less.
