Why this is the answer
The correct answer in the official bank: Yes, the connection of a trailer or a semi-trailer requires the performance of a brake response check when starting to drive.
After coupling a trailer or semi-trailer, the air lines or brake connections may not be properly attached, so the driver must check brake response right at the start of driving, at low speed. Normal air pressure alone does not prove the trailer brakes actually work. No brake-testing facility is needed, because the driver can perform this check personally.
