Minnesota Blue Card Practice Test

What is the safe distance to stop from a vehicle when its signal lights are on and its arm is extended?

1. 10 feet

2. 20 feet

3. 30 feet

4. 40 feet

The correct answer is: 20 feet

When a vehicle's signal lights are on and its arm is extended, it typically indicates that the vehicle is either stopping to load or unload passengers, particularly in the context of school buses. The law requires drivers to maintain a safe distance when approaching such a vehicle to ensure the safety of children and other passengers who may be entering or exiting the bus. Stopping at a distance of 20 feet is the legally mandated safe distance from a vehicle exhibiting this signal. This distance allows sufficient space to protect children and others from potential harm as they board or depart the vehicle. Sufficient distance is critical to ensure that all passengers can do so safely, reducing the risk of accidents. While options for greater distances might seem safer in theory, 20 feet is the established legal and practical standard within Minnesota law regarding stopping for vehicles with extended arms. It balances safety with the need for efficient traffic flow.
