Sure! Here are the signs a driver may be confused or impaired from the options given:
1. Erratic driving: If a driver is swerving in and out of lanes, driving at inconsistent speeds, or making sudden turns without signaling, it could be a sign of confusion or impairment.
2. Slowing or stopping suddenly and without warning: Abruptly slowing down or stopping without a valid reason can indicate a lack of focus or impaired judgment, which are signs of confusion or impairment.
These behaviors can pose a risk to the driver and others on the road. It is important for drivers to remain alert, follow traffic rules, and avoid driving under the influence of alcohol or drugs to ensure safety on the road.
