Weather, visibility and night driving: key rules to remember

Environmental hazards
- In B.C., fog, heavy rain and snow create difficult conditions; slippery roads can lead to multi-vehicle crashes.
- Best option in extreme weather: stay home or take the bus.
- Fog, rain or snow can blind you and badly reduce road information.
Low visibility; glare and shadows
- In certain fog, fog lamps may be used instead of headlamps if that helps visibility (headlamps off, fog lights only).
- Low visibility: slow down, extra space margins, scan more carefully, low beams in rain/snow/fog, don't pass in extreme weather, pull over somewhere safe (not blocking roads) until visibility improves, use the defroster (window partly open if needed), clear snow and ice before leaving, keep wipers/washers working.
- Glare/shadows: slow before entering tunnels; remove sunglasses and turn on headlights in tunnels; sunglasses and visor by day; clean windows; rear-view mirror in night position; good following distance at night to reduce glare your headlights cause.
Wet roads; loss of traction; rain
- Tires should be in good condition, properly inflated and suited to conditions.
- Wet roads: slow down, more following distance, allow at least twice the normal braking distance, brake gently.
- Never use cruise control in wet or slippery conditions.
- Loose gravel, wet leaves, mud or sand also cause low traction.
- Rain causes loss of traction and hydroplaning. Roads are most slippery at the start of a rainfall (rain + oil film); the film washes away with continued rain, but stays longer if the rain is light or it hasn't rained for a long time.
- Hydroplaning: tires float on water; steering and braking control is lost instantly; more likely at higher speed; sign: steering suddenly feels very light.
Hydroplaning; deep water; ice and snow
- Prevent hydroplaning: check tread and inflation, scan for large puddles, slow down especially in heavy rain. Low pressure or worn tread make it more likely.
- If hydroplaning: decelerate and keep straight; never brake.
- Deep water can stall the vehicle and damage the engine or transmission; consider another route; otherwise drive through very slowly; afterwards lightly apply brakes for a short distance to dry them.
- Moving water deeper than half a metre can carry a car away.
- Ice/snow: wheels spin when accelerating and lock when braking. Temperatures near freezing are more dangerous than colder ones because ice forms unexpectedly and may be invisible.
Handling ice and snow
- Plan: check the forecast (staying home may be wisest), winter-suitable tires, carry chains and know how to mount them — snow tires and/or chains are legally required on many B.C. roads in winter; carry sand or a piece of carpet.
- See: clear snow/frost from windows and mirrors, wipers and lights; scan further ahead.
- Think: plan manoeuvres further ahead. Do: slow down, accelerate gently, test brakes and steering at very low speed, chain up before you spin out on a hill.
- Stopping on ice can take 10 times the normal braking distance.
- Black ice: moisture freezing on the road, normally invisible; be suspicious if asphalt looks shiny and black instead of gray-white.
- Shaded areas can stay icy; bridges and overpasses ice before other surfaces; intersections ice quickly from car exhaust and packed snow.
Ice and snow (continued); stranded or snowbound
- Use a designated chain-up area (chaining on a hill is extremely difficult).
- If wheels lock, ease off and re-apply the brakes to keep steering control.
- Slow before curves (braking in curves can cause a skid); low gear down icy hills; no cruise control on ice/snow; extra space; avoid passing; use the lane with the least snow/ice; gentle steering.
- Dizzy or drowsy with the engine running: possible carbon monoxide poisoning — engine off, fresh air.
- Stranded: stay with the vehicle unless sure you can reach help; run the engine for heat only about five minutes every hour; check the exhaust isn't blocked; keep one window slightly open; at least one person awake at all times.
Turbulence; night hazards; headlights
- Crosswinds, headwinds and tailwinds affect steering; a passing tractor-trailer can push a vehicle.
- Turbulence: slow down, grip the wheel firmly with both hands, watch motorcycles, small cars, campers and trailer-towing vehicles, allow extra side space when passing a large truck or trailer.
- At night you see less, are seen less and judge distance worse.
- Low beams light up to 30 m ahead; high beams about 100 m.
- Headlights required from 30 minutes after sunset to 30 minutes before sunrise.
Headlight rules; night driving; overdriving
- Illegal to drive at night on parking lights or daytime running lights instead of headlights.
- Dim high beams within 150 m of another vehicle, whether meeting or following.
- Headlights also required when visibility is under 150 m (fog, heavy rain).
- Night strategies: keep eyes moving; glance to the right edge of the road to avoid oncoming glare; set rear-view mirror for night; set outside mirrors so the vehicle body is just out of view; interior lights off, panel lights low; clean windows and lights; stay alert; slow down; increase following distance.
- Overdriving headlights: going too fast to stop within the distance your headlights light up — especially dangerous on curves.
