Question 1

When does a Missouri driver NOT have to stop for a school bus with its red lights flashing?

Accepted Answer

Opposite direction on a 4+-lane highway, opposite direction on a divided highway with separate roadways, or a bus stopped in a loading zone — Missouri lists three exceptions: traveling the opposite direction on a highway divided by a median with fully separate roadways, traveling the opposite direction on a highway with four or more total lanes, or the bus being stopped in a school loading zone where students don't cross the roadway.

Question 2

When is a Missouri driver required to change lanes -- rather than just slow down -- for a stationary emergency vehicle with red or red-and-blue lights on?

Accepted Answer

Only on a roadway with 4+ total lanes and 2+ lanes running the driver's own direction — Missouri only requires a lane change away from a stationary emergency vehicle when the roadway has at least four lanes total with at least two running your direction -- otherwise, the rule is to reduce speed and proceed with caution.

Question 3

What fine applies specifically to speeding or passing inside a Missouri work or construction zone?

Accepted Answer

A minimum $250 first offense, $300 minimum after that, on top of any other fine — Under Section 304.582, RSMo, speeding or passing in a Missouri work zone brings its own added fine: a minimum of $250 for a first offense and $300 for a second or later one, in addition to any other fine the violation carries.
