Which behavior might reinforce suspicion of DWI when observing a motor vehicle?

The behavior that reinforces suspicion of DWI when observing a motor vehicle is an attempt to flee. This action is indicative of potential criminal behavior and raises immediate red flags for law enforcement officers. When a driver attempts to evade authorities, it suggests they may be hiding something, such as impaired driving due to alcohol or drugs. This instinct to escape can signal to officers that the driver might not just be exhibiting poor driving behavior but may also be involved in other illegal activities.

While excessive acceleration, constant lane changes, and driving with lights off can all be associated with impaired driving, an attempt to flee is a more direct indicator of a driver who is potentially impaired and aware of their risky situation, thus elevating the level of suspicion significantly.
