That time of year again when the Aussies and Kiwis head across the Pacific. I've posted many times here about winter driving so you can search if you want more detail. This one hits the key points and then I thought I'd add some detail on road rules that you guys will find slightly different from home. Golden Rule For Winter Driving: Don't have a schedule. If you have a tight schedule, you are tempted to hurry. Not good when it's slimy out there. Knowing when to simply stay off the road is a really powerful tool that is no longer at your disposal if you must be somewhere at a certain time. No sudden moves. Gentle, smooth inputs on the pedals and wheel make for a stable vehicle. Gears are for slowing, brakes are for stopping. It's not quite as cut and dried as that, but you get the picture. Use gears for slowing smoothly and gently. No such thing as a manual rental car in nth america, but autos have gears too. Use them. The road down from ski resorts is almost always steep and twisty for an extended period of time. Put the vehicle in the appropriate gear (2nd if it is a 4 speed, likely 3rd if it has 5 or 6) and let the engine take a load off those brakes. Near-freezing is the slipperiest snow. Dry cold snow is relatively grippy. Be wary when the temp is hovering right around freezing. Road traction will be slippery and, worse yet, variable. Places in the sun will melt and re-freeze, shady spots, not as much. Bridge decks change temp fast because of air circulation on all sides. Warm, melting snow is mucky and there will be a constant splatter of fine spray on the windscreen from other vehicles. Make sure before going on a highway trip that you have a full tank of washer fluid, and please don't put water in there. Servos have 'windshield antifreeze', about $5 for 4 litres. Have a backup one in the boot because you are in deep poo if you get stranded out between towns with no washer fluid.
