Can I apply for a car license plate if I have a motorcycle that hasn't been scrapped?

If you have a motorcycle that hasn't been scrapped, you cannot apply for a car license plate. According to relevant regulations, if there is any motor vehicle under the owner's name that has not passed inspection or has not been scrapped on time, the system will automatically lock it. Only after the owner completes the vehicle inspection or the scrapping procedures can they proceed with new vehicle registration, transfer registration, and other procedures. The following are some precautions regarding vehicle license plate application: 1. Determine the type of license plate to apply for: After deciding whether to apply for a local or out-of-town license plate, pay the purchase tax according to regulations. The vehicle purchase tax should be paid at the vehicle's registered location. If you choose a local license plate, the tax must be paid locally; if you choose an out-of-town license plate, the tax must be paid out of town. 2. Fully understand relevant information: Before purchasing a new energy vehicle, determine whether a charging pile can be installed and understand relevant information. You should also learn about the application process for special license plate quotas, fiscal subsidy standards, and other important information.

What are the methods and standards for checking engine oil?

Here is an introduction to the standard method for checking engine oil: Determining the oil level: Park the vehicle on a relatively level and flat road surface; After parking for 10 minutes, pull out the dipstick and observe the position of the oil between the upper and lower marks on the dipstick to determine whether the oil in the oil pan needs to be added. Remember not to pull out the dipstick immediately after parking to check the oil level in the oil pan, as the result at this time cannot accurately reflect the actual oil level in the oil pan. Do not overfill: If the oil level in the oil pan is already below the lower mark on the dipstick, it is necessary to add oil in time. Unscrew the oil filler cap and add an appropriate amount of the same brand and grade of oil as that in the oil pan. Wait for 10 minutes, then check whether the added oil meets the requirements. The oil level should be between the upper and middle marks on the dipstick. Remember not to add too much oil. If the oil level exceeds the upper mark on the dipstick, the engine will expel oil from the breather and produce blue smoke from the exhaust pipe when operating under this condition.

Can You Wear Sunglasses While Driving?

Yes, you can, but wearing sunglasses reduces the amount of light reaching your eyes, making objects ahead appear darker, which may not be conducive to drivers clearly seeing road conditions. Below is relevant information about wearing sunglasses while driving: Polarized lenses: Polarized lenses are designed to allow only directional light to pass through. To put it vividly, it can be likened to the effect of blinds. When the blinds are adjusted to a horizontal position, you can see the scenery outside while being unaffected by glaring sunlight. Therefore, lenses with polarization can filter out dazzling glare caused by scattering, refraction, reflection, and other factors. Gradient sunglasses: Also commonly known as "gradient" sunglasses, these are more user-friendly compared to solid-color sunglasses. Since the purpose of wearing sunglasses is to block glaring sunlight, and sunlight comes from above, the darker upper part and lighter lower part ensure that you are not dazzled by sunlight while still being able to see objects below clearly. However, such sunglasses still have shortcomings for driving purposes.

Can You Cross a Solid Yellow Line?

Solid yellow lines cannot be crossed. The purpose of solid yellow lines is to prohibit vehicles from crossing or driving over the line in both directions. Solid yellow lines are typically marked on roads with only one lane in a single direction or one motor vehicle lane and one non-motorized vehicle lane, as well as on sections where overtaking is prohibited due to other hazards. Yellow lines are used to separate lanes in different directions, usually painted in the middle of the road, acting like a divider to separate the road into two directions. Double solid yellow lines: These are used to divide roads with two or more motor vehicle lanes in each direction without a central divider, strictly prohibiting vehicles from crossing the line to overtake or driving over the line. Center double yellow dashed lines: These are usually placed at intersections, often found on roads with low traffic volume. On sections with center double yellow dashed lines, vehicles may cross the line to enter the intersection after confirming the surrounding safety. Double yellow lines with one solid and one dashed: In this marking, one side is dashed, and the other is solid. The dashed side allows crossing the line for overtaking or making a U-turn, while the solid side prohibits crossing or driving over the line.
