About Level crossing: markers, the Saint Andrew's cross, and the red flashing light: which statement is WRONG?

One Saint Andrew's cross means one track, two crosses mean two OR MORE tracks at that same crossing — not two crossings.
Both types of level crossing have flashing lights and alarm bells; the only difference is the presence or absence of barriers.
Each diagonal stripe represents 80 metres: three stripes at 240 m, two stripes at 160 m, one stripe at 80 m before the crossing.
✓ You only need to stop for a level crossing once the barriers start to lower, not already at the red flashing light.

Correct answer: You only need to stop for a level crossing once the barriers start to lower, not already at the red flashing light.

Explanation

You must stop as soon as the crossing lights start flashing red and the alarm bells start ringing; the barriers only lower a few seconds later
