Practise pavement markings →Read colour before deciding what the line separates
Yellow lines divide opposing traffic; white lines separate traffic moving in the same direction. This distinction tells you whether a move can put the car into an oncoming lane. Do not treat every painted gap as an ordinary same-direction lane change.
Check the markings on your approach and the signs governing the location. This guide concerns overtaking; it is not a complete statement about every driveway turn, road configuration or temporary direction by an authorized person.
Source: SGI — Directional dividing lines ↗A permitted pass still needs sight distance and space
SGI warns against passing at a hill crest, before a curve, at intersections or wherever the available view is limited. A broken line cannot reveal an approaching vehicle hidden beyond a rise. Wait when the whole manoeuvre cannot be judged safely.
The speed limit remains in force during a pass. SGI also says not to pass a vehicle stopped at an intersection for pedestrians. When returning, see the passed vehicle in the inside rearview mirror, then signal and check mirrors and the blind spot.

Original worked cases
A slow car is ahead beside a solid yellow line. An empty view of the opposite lane does not remove the marking restriction. The driver waits.
A broken marking appears before a blind rise. The line alone is not enough: the driver cannot establish the necessary clear distance beyond the crest.
A proposed pass would require exceeding the posted maximum. SGI does not provide a speeding exception for overtaking. A later passing lane may offer a better opportunity.
Include the return in the plan
Passing is not complete when the front of your car reaches the other vehicle. A safe return still needs space and observation. Cutting in early can create a new conflict even if entering the oncoming lane was initially possible.
Practise markings and highway questions together. For each answer, identify whether the obstacle is a prohibition, visibility, speed or insufficient return space. These independent exercises remain free and do not reproduce official exam questions.
