What are the seven essentials for driving on icy and snowy roads?

[DeEsther]

Seven essentials for driving on icy and snowy roads include: preventing poor vehicle condition, preventing abrupt starts, preventing insufficient observation, preventing tailgating, preventing rapid steering, preventing sudden braking, and preventing improper parking. Meaning of preventing poor vehicle condition: Before driving, the vehicle should be thoroughly inspected to ensure it is in good condition, especially the steering and braking systems, which should be effective and reliable. There should be no deviation or uneven braking when applying the brakes. The tire pressure should be set to the lower limit of the specified value, and the pressure should be the same for both left and right tires. Tires with worn-out treads should be replaced promptly. To prevent skidding, the front and rear wheel brakes should be adjusted for synchronized braking. Since icy roads are very slippery, snow chains should be installed when driving. The snow chains should be evenly tightened and symmetrically placed on both sides. Cargo should be evenly distributed, ensuring equal load on both sides of the tires. Additionally, when driving on icy and snowy roads, it is advisable to carry necessary anti-slip and warming supplies. Meaning of preventing abrupt starts: If the tires are found to be frozen to the ground when starting, use a pickaxe to remove the ice, snow, and mud around the tires to prevent damage to the tires and transmission components. When starting, the clutch can be partially engaged, and the accelerator should be gently pressed to allow the engine to output minimal power without stalling, adapting to the icy and snowy road conditions and avoiding wheel spin. If the drive wheels slip, remove the ice and snow beneath the wheels and sprinkle dry sand, coal cinders, or straw under the drive wheels. Alternatively, use a pickaxe to carve "X" or "Y" shaped grooves into the road surface to improve traction.
