Sharing with motorcycles — Missouri Permit Test
Sharing with motorcycles on the Missouri permit test — 6 rules, each with the reason behind it and a question on it while it is fresh.
The rules
You should not share a lane with a motorcycle, because the rider needs the entire lane for safety.
A motorcycle uses the whole width of a lane to dodge a pothole or a gust. Half a lane is not enough room to ride in.

When passing a motorcycle, give it a full lane width and do not squeeze past.
Squeezing by leaves the rider nowhere to go if something happens in front of them.

It is not always easy to judge the speed or distance of a motorcycle.
A small object looks further away and slower than it is. That misjudgment is behind a great many left-turn collisions.

Motorcyclists change speed and lane position for manhole covers, diagonal railroad tracks, road debris, and strong winds, so be ready to react.
What a car rolls straight over can put a motorcycle down. The rider moving suddenly is usually avoiding something you never noticed.
Motorcyclists change speed and lane position when encountering bad road conditions, such as manhole covers, diagonal railroad tracks, road debris, or in strong winds. Be ready to react.
On residential streets, especially those with parked cars, travel at or below the speed limit depending on sight distance.
Parked cars hide everything low and small. The posted limit is a ceiling there, not a target.

On the test
How much of a lane does a motorcycle need?
The entire lane. A motorcycle uses the whole width of a lane to dodge a pothole or a gust. Half a lane is not enough room to ride in. Missouri Driver Guide, p.28: “You should not share a lane with a motorcycle. The motorcyclist needs the entire lane for safety reasons.”
How this works
Most practice tests hand you a bank of questions and leave the manual somewhere else. This one puts them together.
You read one law and the reason behind it, then answer a question on that law while it is still fresh. Get it right and you move on; get it wrong and you have found the gap while it is cheap to fix, not on the morning of the exam.
Learning one rule at a time, and proving it immediately, is what turns a manual you skimmed into something you actually know — and it makes studying feel like getting somewhere rather than like waiting to find out.
