applying your smart driving skills do  Space margins and speed control  driving tip Trains  see  96 You may not be able to see a train coming if visibility is poor,  but you may hear its whistle. But remember that trains are not  required to sound a whistle at every crossing. Watch for clues  — lots of clues warn you of a railway  crossing ahead:  Every year people die or are seriously injured in collisions  between vehicles and trains, so you need to be careful  when approaching a railway crossing. Most trains require  approximately two kilometres to stop — never try to beat one.  improving the roads for everyone. Check radio, television and  websites for the latest traffic reports and updates to find out  what is happening on the roads within your area, and along  your intended route. Consider taking an alternate route. Slow down  — the road surface may be uneven or unpaved,  so you need to slow down. You must obey construction zone  speed limits. Traffic fines are double in construction zones.  Stop when directed  — stop when directed to do so by  traffic control persons or other traffic control devices. In some  construction zones, you may need to wait for a pilot car to  escort you through the work zone.  Unnecessary idling wastes  gas and causes emissions  that degrade air quality  and contribute to climate  change. If you are directed  to stop in a construction  zone, turn off the engine.  Idling for more than 10  seconds costs more than  turning the engine off. Allow following distance  — leave plenty of following distance  between your vehicle and the vehicle immediately ahead. Avoid  changing lanes in a construction zone.  Allow side margins  — leave space between you, the construction  crews and their equipment in the construction zones.  •  Advance warning signs  — these signs alert you to an  upcoming crossing, and tell you to look, listen and slow down  because you may have to stop. They are usually posted in  locations where you cannot see an upcoming railway crossing  (for example, on hilly or curvy roads). An advisory speed sign  below the advance warning sign may show that the safe road  speed is less than the posted speed. •  Pavement markings  — at the approach to some railway  crossings, you may see a painted “X” on the pavement.  Some crossings also have flashing lights, a bell and gates. If  the light and bell are activated or the gate is down, it means  a train is approaching.
