Depending on the type of crossing motorists will require, to varying degrees, the ability to see an approaching train. At crossings with passive warning signs (crossbucks) motorists rely almost entirely on their ability to see an approaching train when deciding to proceed.
Transport Canada has recommended the following minimum sightlines:

1. These are recommended minimum distances for typical crossings. To allow a vehicle stopped at the crossing sufficient time to accelerate and safely clear the crossing , they must be adjusted for the road geometry and type of vehicle crossing where: - Gradients within 8 m of the rail exceed 5% - The crossing angle is less than 70º or greater than 110° - Heavy or long trucks cross regularly - Two or more tracks are in the crossing 2. Where heavy vehicles operate on long descending approaches, increase "H" to "stopping sight distances" calculated in accordance with the Transportation Association of Canada "Geometric Design Guide." | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
