Bicycle and work zone signs — Alabama Permit Test
Bicycle and work zone signs on the Alabama permit test — 7 rules, each with the reason behind it and a question on it while it is fresh.
The rules
A MAY USE FULL LANE sign means a person on a bicycle may use the full lane if the travel lane is narrow.
A lane too narrow to share safely is one where a rider is safer in the middle of it.
Cyclist may use full lane if travel lane is narrow.
Shared Lane Markings, or sharrows, tell road users that people on bicycles might occupy the travel lane.
The marking warns drivers to expect riders in the lane, not just at the edge.
Shared Lane Markings (Sharrow) inform road users that people on bicycles might occupy the travel lane.
A ROAD CONSTRUCTION sign means you are about to enter a road construction area: look out for flaggers, one-way traffic, other signs or obstructions, and proceed with caution and obey signs and instructions.
Work zones change from day to day, so you cannot drive them from memory.
Be on the look-out for flagman, one-way traffic, other signs or obstructions.
A flagger symbol sign means a flagman is ahead.
The flagger may stop you, so be ready to slow down and follow their signals.
Flagman ahead.
A worker symbol sign means workers are in or near the roadway.
People working on the road may be just feet from passing cars.
Workers in or near roadway.
A MOWERS AHEAD sign means mowing equipment is ahead.
Mowers move slowly along the edge of the road and can throw debris.
Mowing equipment ahead.
Large flashing or sequencing arrow panels may be used in work zones day and night to guide drivers into certain lanes and show that part of the road ahead is closed.
The arrow tells you which way to move over before you reach the closed lane.
Large flashing or sequencing arrow panels may be used in work zones both day and night to guide drivers into certain traffic lanes and to inform them that part of the road or street ahead is closed.
On the test
What does a BICYCLES MAY USE FULL LANE sign mean?
A cyclist may take the whole lane if it is narrow. A lane too narrow to share safely is one where a rider is safer in the middle of it. Alabama Driver Manual, p.50: “Cyclist may use full lane if travel lane is narrow.”
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.
