Motorcycle lane sharing — New Mexico Permit Test
Motorcycle lane sharing on the New Mexico permit test — 4 rules, each with the reason behind it and a question on it while it is fresh.
The rules
Cars and motorcycles each need a full lane to operate safely.
A bike squeezed into part of a lane has no room to dodge a door, a turn or a hand out a window.
Cars and motorcycles need a full lane to operate safely.
Lane sharing, a car and a motorcycle riding side by side in one lane, is usually prohibited.
A driver who squeezes in next to a bike leaves the rider with no space if either one moves.
Lane sharing is usually prohibited.
To keep drivers from squeezing by, a rider keeps a center-of-the-lane position.
A bike at the edge of the lane leaves a gap that tempts a driver to pull up alongside it.
Keep a center of the lane position whenever drivers might be tempted to squeeze by you.
Drivers are most tempted to squeeze past a motorcycle in heavy, bumper-to-bumper traffic.
In slow, packed traffic a driver may see the spare room beside a bike and try to use it.
Drivers are most tempted to do this in heavy, bumper-to-bumper traffic, if they want to pass you, when you are preparing to turn at an intersection, or when you are getting in an exit lane or leaving a highway.
On the test
How much lane space does a motorcycle need to operate safely?
A full lane. A bike squeezed into part of a lane has no room to dodge a door, a turn or a hand out a window. New Mexico Driver Manual, p.36: “Cars and motorcycles need a full lane to operate safely.”
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.
