A dead car battery typically requires about 4 hours of driving to fully recharge. Here are some precautions for car battery usage: 1. Turn off all lights before shutting down the engine. Older car models do not support automatic power-off after engine shutdown, so manually turn off headlights and interior reading lights before shutting down. 2. Turn off the air conditioning and audio system before shutting down. The air conditioning system involves the compressor and blower, and the audio system is also a high-power electrical device. If not turned off before shutdown, they will automatically start the next time the car is turned on, placing a heavy burden on the battery and causing damage. 3. Avoid leaving the car parked for extended periods. The battery installed in the car will self-discharge over time when left idle. It is best to drive the car at least once a week, with a trip duration of at least 20 minutes, to allow the battery to recharge while driving. 4. Close all windows before shutting down the engine. The power for operating car windows and sunroofs comes from the battery, so it is advisable to close all windows before shutting down the engine.

What license is required for large vehicles?

Large vehicle license refers to the B2 license. Below are the vehicle types permitted with a B2 driver's license and important considerations for driving large trucks. Vehicle types permitted with a B2 license: The B2 license allows the holder to operate heavy-duty, medium-duty trucks or large, heavy, and medium-sized specialized operation vehicles. Heavy-duty and medium-duty trucks are primarily cargo trucks, such as the large dump trucks commonly seen on roads carrying construction waste, which fall under the category of heavy-duty trucks. Important considerations for driving large trucks: When driving heavy-duty trucks, it is essential to understand their characteristics. Heavy-duty trucks have a large mass and high inertia; a high center of gravity leading to significant centrifugal force. They have a long body, occupying more space. The long wheelbase results in a large inner wheel difference. They use air brakes, which provide quick braking response. The steering wheel is larger and responds slower compared to smaller vehicles. They have multiple gears (six or more) with small gear gaps, making the operation more complex and demanding than driving smaller vehicles.
