Title: TRANSPORTATION TUESDAY


1
TRANSPORTATION TUESDAY
  • Driving safely means adjusting to road and
    traffic conditions.
  • When you cant control the conditions, you must
    control your vehicle.

2
SNOW ICE
Slow down at the first sign of rain, snow or
sleet.
  • How slow?
  • At least 10 mph for rain
  • About half normal speed on packed snow
  • Slow to a crawl on ice - this is the most
    dangerous surface and sudden actions will quickly
    make you skid
  • REMEMBER
  • on corners or bends - you will skid more easily
  • brake progressively on the straight part so that
    your vehicle is slow enough to take the bend
    safely
  • steer gently round the corner - avoid sudden
    movements
  • find a safe place on the straight to gently test
    your brakes
  • if the steering is unresponsive then you are
    probably on ice
  • ice or snow?
  • tyres on ice make virtually no noise
  • tyres on snow make a crunchy or slushy sound

SAND, GRAVEL, DIRT TRACKS
  • You do not have as much grip on sand, gravel or
    dirt as you do on asphalt (black top) roads
  • slow your vehicle
  • stay back from other vehicles - beware of
  • dust clouds that hide what is in front and at the
    side of you
  • stones flying from other vehicles tyres
  • give yourself extra space and time for overtaking
  • accelerate and brake gently
  • if you lose control and leave the road
  • brake gently to slow the vehicle gradually
  • do not try to steer back onto the road - this may
    cause you to flip over - keep in a straight line
    if you can
  • allow the vehicle to come to a complete stop
    before attempting to rejoin the road
  • beware of ruts that will take control of your
    tyres

WATER
  • Your vehicle can take as much as twice as long to
    stop on a wet road as compared to a dry road
  • stay back so that you can
  • see and plan ahead
  • avoid spray from other vehicles
  • stop in time

If you have driven through deep water - find a
safe place to check your brakes. Gently
applying pressure for a while will help dry out
brakes that are wet.
  • Hydroplaning when your tyres lose contact with
    the road
  • most tyres have good traction up to about 35 mph
  • when you go faster, your tyres ride up in the
    water (like waterski-ing)
  • in heavy rain your tyres may lose contact with
    the road at 50mph
  • worn tyres will lose traction at much slower
    speeds
  • Recover from hydroplaning
  • ease your foot off the gas pedal you will feel
    the tyres gripping again
  • keep the steering wheel straight only try to
    turn if its an emergency
  • if you must turn, do it SLOWLY or you will SKID
  • do not try to stop or turn until your tyres are
    gripping to road again

in all bad weather conditions
  • stay well back from all other vehicles - if
    someone cuts into the space, fall back to keep a
    safe distance
  • keep your windscreen clear
  • think twice before overtaking - you dont know
    what the conditions ahead are
  • put your headlights on dipped
  • do not put on your hazard lights unless you are
    in an accident
  • make sure your tyres are in good condition and at
    the correct pressure
  • make sure someone knows your route and when you
    expect to arrive - and what to do if you miss
    your deadline

if in doubt dont go out
