What Violations Do Electronic Police Capture?

Electronic police capture violations such as illegal U-turns, improper lane changes, occupying bus lanes, driving against traffic, running red/yellow lights, and solid line lane changes. Below are detailed introductions to other monitoring methods for detecting violations: 1. Traffic flow monitoring: Mounted on thin poles. Used to record traffic volume on road sections at different times of the day, submitting data to traffic management departments for adjusting traffic light intervals, not for recording vehicle violations. 2. Speed trap cameras: Installed at marked locations, relatively easy to spot, but may also be placed in concealed areas of highways, making them hard to identify. If such a camera flashes when passing on the highway, it indicates speeding. 3. Illegal parking cameras: Frequently seen in residential alleys and high-traffic areas, they can also monitor vehicles driving against traffic or parked illegally for extended periods, with an accuracy rate exceeding 90%. The lenses can zoom and automatically adjust image size, with a visible range of 200 meters. 4. Multiple cameras on a single pole: Typically installed between intersections, most commonly used on main roads with speed limits of 60 km/h. Some are hidden under bridges.

Squealing Noise When Braking

Here are the specific reasons for sharp squealing noises when braking: 1. Improper brake pad installation: When installing new brake pads, the old brake disc was not resurfaced, resulting in a poor fit. A poor fit or installing new pads without resurfacing the old disc causes the new pads to directly rub against the uneven surface of the old disc, leading to uneven wear on the new pads. 2. Brake system malfunction: There may be a defect in the brake system itself, causing the brake pads to only partially contact the brake disc. This increases the pressure per unit area during braking, resulting in abnormal noises. It is recommended to inspect components such as the caliper and guide pins. 3. Presence of foreign objects: Foreign objects cause an uneven contact surface, leading to abnormal noises.

Is It Safe to Buy a Car with an Expired Mortgage?

A car with an expired mortgage can be purchased, but it carries significant risks. If the mortgagor repays the loan on time, the mortgage right will not be enforced. However, if the mortgagor fails to repay the loan on schedule, after the debt repayment period expires, the mortgagee can apply to auction the car to repay the debt. In this case, the buyer can only demand a refund from the mortgagor and has no right to refuse the auction. Additional Information: 1. Legality of Mortgaged Cars: Mortgaged cars are divided into fully paid mortgaged cars and non-fully paid mortgaged cars. A fully paid mortgaged car is one where the owner is unwilling or unable to repay the financial company and does not cooperate with the transfer of ownership. The financial company legally transfers the debt, making such a mortgaged car safe and legal to purchase. A non-fully paid mortgaged car is still under mortgage status with the vehicle management office and the bank. Such cars should be purchased with caution, as they may eventually be seized if the owner fails to repay the car loan. 2. Sources of Mortgaged Cars: Mortgaged cars are properties pledged by owners or homeowners when they urgently need cash and take loans from financial institutions. There are two main sources of mortgaged cars: one comes from state-recognized investment companies, guarantee companies, or pawnshops, and the other originates from private financial companies as loan collateral.

How to Check Car Battery Voltage?

There are several methods to check car battery voltage: 1. Check the observation port. The colors visible in the observation port are generally divided into three types: green, yellow, and black. Green indicates sufficient charge, yellow indicates slight discharge, and black means the battery is nearly dead and needs replacement. Depending on the design of the battery manufacturer, there may be other forms of charge observation. Refer to the label on the battery for specific instructions. 2. Measure the voltage. Use a battery tester or multimeter to measure the battery voltage. Under normal circumstances, the no-load voltage of the battery is around 13 volts, and the full-load voltage generally does not drop below 12 volts. If the battery voltage is low, it may cause difficulty or failure in starting the vehicle. If the battery remains in a low-voltage state for a long time, it will prematurely fail. 3. Inspect the appearance. Check if there is obvious swelling, deformation, or bulging on both sides of the battery. Once this occurs, it indicates that the battery's lifespan is more than halfway over. 4. Examine the terminals. Look for any white or green powdery substances around the battery terminals. These are battery oxides. High-quality or new batteries will not easily develop these oxides. Once they appear, it means the battery's performance is starting to decline. If these oxides are not removed in time, they can cause insufficient generator output, leading to a discharged state of the battery. In severe cases, this can result in early battery failure or failure to start the car.

What Does the Battery Number Mean?

Taking a battery with the model number 6-QAW-54a as an example: 1. 6: Indicates that the battery consists of 6 individual cells, each with a rated voltage of 2V, so the entire battery is 12V. 2. Q: Indicates the battery's purpose. Q stands for automotive starting battery. M is for motorcycle batteries, JC for marine batteries, HK for aviation batteries, D for electric vehicle batteries, and F for valve-regulated batteries. 3. A and W: Indicate the battery type. A stands for dry-charged batteries, and W for maintenance-free batteries. If there is no corresponding designation, it is a standard battery. 4. 54: Indicates the battery's rated capacity is 54Ah. 5. Subscript a: Indicates the first improvement to the original product. If the identifier is b, it represents the second improvement (and so on).

What Are the Causes of Water Leakage in a Car Trunk?

Water leakage in the trunk can be caused by the following reasons: 1. Worn or Aged Sealing Strips: Worn or aged sealing strips, or trunk deformation, can lead to water leakage. It is necessary to check whether the tailgate rubber strip shows signs of aging, wear, or cracking. If the vehicle has been involved in an accident before and leaks after repair, check whether the sealing rubber strip applied post-repair is not tight enough or if there are cracks in the repaired area. 2. Detached or Damaged Sealing Strips: If the sealing strip around the rear taillight connector becomes detached or damaged, water can flow into the trunk from the taillight. 3. Leaking or Clogged Drain Pipes: Some cars have sunroof drain pipes running through the trunk. If these drain pipes leak or become clogged, it can also cause this issue.
