What level BAC or higher prevents a vehicle from starting in Tennessee?

• A. 0.020
• B. 0.08
• C. 0.00
• D. 0.10

Answer: (A)

A BAC of 0.02% or higher prevents starting the vehicle because Tennessee uses a zero-tolerance rule for underage drivers: even a small amount of alcohol can prohibit starting the car. This threshold is much lower than the general DUI limit, which is 0.08% for driving, and it targets preventing underage or otherwise restricted individuals from beginning any operation of the vehicle. So the 0.02% mark is the minimum level at which starting the vehicle is not allowed. The other values don’t fit because 0.00 would allow starting with no alcohol, and the higher values (0.08, 0.10) relate to driving under the influence, not specifically to the act of starting the vehicle.
