before each trip when going downhill in a vehicle with an automatic transmission you should select a low range to get greater engine braking what are some things to do if you are being tailgated avoid quick changes of speed or direction to be sure that you know what is happening on the highway ahead of you don't focus on the mirrors too long exhaust system parts should not rub against fuel system parts tires or other moving parts of the vehicle how do you test hydraulic brakes for they're stopping action go about five miles per hour and then push the brake pedal firmly a third good rule for using turn signals is if you don't have self cancelling turn signal indicators remember to turn off the turn signal indicator after you have completed your turn you may part me what may rust around the willness mean let me read it again what what may or what does rust or what does it possibly mean what does rust possibly mean around the wheel nuts I'm just read that as it says here what may rust

engine speed and Road speed if you have to stop your vehicle in the road to load cargo or passengers you should flash your brake lights to warn drivers behind you when do empty trucks usually you'll require greater stopping distance oh poor me I read that again it's not win but why why do empty trucks usually require greater stopping distance empty trucks can bounce and lock up their brakes what

bracing the purpose of cargo blocking and bracing is to keep cargo from sliding and falling and getting out of balance you when traction is poor such as in rain or snow you should for me how should you speed up very gradually where do you place the three reflector triangles on a divided highway place them all to the rear within ten feet 100 feet and 200 feet okay so here's the diagram divided rear 10 100 200 feet how often should cargo inspections be made after every break during driving when driving over 40 miles per hour how much space should you keep in army how much space should you try to keep in front of your vehicle at least one second for 10 feet of your vehicle plus one second what is a vehicle condition report a list of problems found by you what are two of the three good rules for using your turn indicators or your turn signal indicators signal early and signal continuously before starting down a hill you want to be sure that you are in the proper gear you downshift before starting down the hill how does tire pressure affect hydroplaning hydroplaning is more likely to occur when tire pressure is low when should you help out other drivers by signalling that it is safe for them to pass never signal to let others know it is safe to pass what is probably your best driving speed traffic is moving at 35 miles per hour in a 55 mile per hour zone 35 miles per hour is probably your best driving speed so basically it's saying match your speed to the flow of traffic speed but don't go over the speed limit turned on brake returns apply their power whenever you let up all the way on the accelerator pad pedal for me what is a minimum number of tie downs you that you should have you should have at least two tie downs should you turn the retarder off when the road is wet or snow-covered yes the retarder can cause your vehicle to skid slight melting will make ice wet what is more slippery wet ice is more slippery I suppose it means what is more slippery than ice or water saying wet ice is more slippery at dusk or dawn or in rain or snow when it's difficult for other drivers to see you you might turn on your low beam headlights okay since air pressure increases with temperature pressure for me since not temperature pressure but temperature increases let me just read that again since air pressure increases with temperature increases you should leave the warm tires alone since the air pressure will decrease when the tires cool off speed limits that are posted at freeways Romney at freeway off-ramps may not be safe speeds for larger vehicles or heavily loaded vehicles how do you know for me how do you test hydraulic brakes for a leak with a vehicle stopped pump the brake pedal three times and then apply firm pressure and then hold for five seconds
