At the entrance to an industrial estate, there is a St. Andrew's Cross with the supplementary sign "Industrial estate, rail vehicles have precedence". What must you remember?

You chose the correct answers. When you see a St. Andrew's Cross with a sign stating "Industrial estate, rail vehicles have precedence," you must always approach the level crossing at a moderate speed, as unexpected rail traffic may appear at any time. Also, rail vehicles have priority at all level crossings marked with this sign. It is important to remember if there is a St. Andrew's Cross, rail vehicles always have precedence; it does not matter if you are in an industrial estate or elsewhere. Motor vehicles only have precedence if there is no St. Andrew's Cross, but that is not relevant with this particular sign combination. This rule prevents accidents and ensures safety at crossings with industrial rail use.
