Construction zones throw a mix of temporary and permanent signage at drivers, and the exam likes to test whether you know temporary signs are just as enforceable.
Here is one worth locking in:
Is a speed limit shown on a temporary road works sign legally binding, or just a suggestion until the sign becomes permanent?
Temporary signs carry the same legal weight as permanent ones, ignoring a temporary speed limit or lane closure sign is treated the same as ignoring a permanent one. Some learners assume "temporary" means "optional," which is exactly the misconception this type of question is built to catch.
Beyond road works, this category also covers school zone signage and how its enforcement hours differ from a standard speed sign.
Your turn. If there is a sign type you keep mixing up, post it here. If you know the answer to someone else's, help them out.
