TUPELO, Miss. (WTVA) -- Drivers traveling on state highways could soon get to their destination faster.
A bill in the Mississippi Legislature aims to increase the speed limit from 70 to 75 miles an hour on some highways.
Five miles faster may not seem like a lot, but at least one mechanic said it can wreak havoc on your wallet.
"Certain cars will get worse fuel mileage, and certain cars will get better fuel mileage. Which one those are are dependent by the vehicle," said Jay Robertson of Tom's Automotive in Tupelo.
Robertson also said traveling just five miles over the speed limit can be especially dangerous during wet road conditions.
"The increase in speed is just a disaster for hydroplaning. The tire has to tread water faster whenever you increase the speed," added Robertson.
Another not so obvious cost is the price to install new speed limit signs.
The Mississippi Department of Transportation said it costs an average of $575 to put up just one speed limit sign.
If the law goes into effect, the state will have to replace all the current speed limit signs at a cost of roughly $200,000.
