It is not safe to keep medical alcohol in the car. The hazards of keeping medical alcohol in the car are as follows: 1. It can easily cause spontaneous combustion and explosion: Medical alcohol left in the car during summer can self-ignite. The common 75% medical alcohol has a flash point of 20 degrees Celsius. In summer, outdoor temperatures can reach over 40 degrees Celsius at noon, and after the car is parked outside under the sun for a period, the interior temperature can rise to over 50 degrees Celsius, making it very easy to trigger spontaneous combustion and explosion of the alcohol. 2. Ensure timely ventilation: Since the flash point of alcohol is only 20 degrees Celsius, if the interior temperature of the car is too high, it may cause combustion. Therefore, it is best not to keep alcohol in the car. If disinfection is needed, find an open area to wipe the car interior with alcohol for disinfection, and ensure proper ventilation inside the car for a period afterward. 3. Do not use alcohol on leather seats: When using alcohol inside the car, if the seats or steering wheel are made of leather, directly spraying alcohol on the leather can cause damage. Alcohol itself is an organic solvent, and on cars with lower-quality leather, it may change the originally smooth and uniform color into a texture resembling that of a jaguar.

What lights to use when driving straight through an intersection at night?

When driving straight through an intersection at night, vehicles should alternately switch between high and low beams. Motor vehicles passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night must alternately use high and low beams as a signal. When driving at night with no street lights, poor illumination, or in low visibility conditions such as fog, rain, snow, dust, or hail, vehicles should turn on headlights, position lights, and rear lights, but must not use high beams when following another vehicle. During foggy conditions, motor vehicles must turn on fog lights and hazard warning flashers. The fog light control lever is typically located below the left side of the steering wheel, with a length comparable to the steering wheel's radius for easy operation while holding the wheel. It controls the switching between high and low beams, left and right turn signals, light activation, and the turning on/off of front and rear fog lights.

What are the procedures for upgrading from a C2 to a C1 driver's license?

The procedures for upgrading from a C2 to a C1 driver's license are: Bring your ID card and C2 driver's license to the service hall of the vehicle management office to apply for the C1 upgrade, correctly fill out the driver's application form, pay the relevant fees, and then obtain a driver's examination skill form to schedule the specific exam date with the staff. Upgrading from C2 to C1 requires retaking all four subjects (Subject 1 to Subject 4) for the C1 vehicle type. Therefore, it is recommended to consider applying for the C1 license initially to avoid having to retake all exams later. The C2 license allows driving small and mini automatic passenger vehicles, as well as light and mini automatic cargo vehicles. In addition to the vehicles covered by the C2 license, the C1 license also permits driving mini, small, and light special-purpose vehicles. In simple terms, the C2 license only allows driving automatic transmission vehicles, while the C1 license permits driving both automatic and manual transmission vehicles, offering a broader range of permissible vehicle types.

What are the causes and solutions for engine overheating?

Engine overheating causes and solutions: 1. Insufficient coolant - If the coolant level is too low, it will severely affect the engine cooling system's heat dissipation. After the engine cools down, check the coolant level and refill to the standard value; 2. Cooling system component failure - This can cause the cooling system to malfunction. Special diagnostic equipment should be used to detect faults, then determine the faulty component based on error codes and replace or repair damaged parts; 3. Radiator clogging - As a crucial component for engine heat exchange located at the front of the vehicle, the radiator can easily accumulate debris like willow catkins on its surface, affecting heat dissipation and potentially causing engine overheating. It's recommended to clean the radiator once every summer.
