Which Came First, Traffic Lights or Cars?

Traffic lights came first. Here is the relevant introduction about which came first, traffic lights or cars: 1. The invention of traffic lights: Traffic lights were invented in 1868. The invention of traffic lights predates cars by 17 years. However, traffic lights were initially invented for the passage of horse-drawn carriages and had nothing to do with cars. 2. The invention of cars: The earliest cars appeared no later than 1885. In 1885, German engineer Karl Benz built a three-wheeled car in Mannheim. This car was equipped with a two-stroke, single-cylinder 0.9-horsepower gasoline engine. Because it featured some basic characteristics of modern cars, such as spark ignition, water cooling, a steel tube frame, leaf spring suspension, rear-wheel drive with front-wheel steering, and a hand brake, it is considered the world's first modern car.

What are the new regulations for motorcycles in 2021?

New motorcycle inspection regulations for 2021 are as follows: 1. Added tread depth inspection: This inspection uses a tire tread depth gauge for measurement. If the tire is severely worn and the depth does not meet the standard, it will fail the annual inspection. After this inspection was added, owners can check their tires beforehand or replace them if the wear exceeds the tread wear indicator line to avoid issues during the inspection. 2. Added wheelbase inspection: The wheelbase test was added to prevent private modifications by owners. Modifying the wheelbase is illegal and should not be attempted. 3. Added vehicle lifting device: This device, commonly seen in 4S shops or repair shops, allows for a clearer observation of the vehicle's chassis condition. For example, an extended wheelbase can be easily identified.

How to Use a Car Battery Charger?

Connect the positive terminal of the battery to the positive terminal of the power source, and the negative terminal of the battery to the negative terminal of the power source. Relevant instructions are as follows: 1. Initial Charging: Charge with the initial charging current until bubbles appear in the electrolyte and the single-cell voltage rises to 2.3-2.4V; then reduce the current to 1/2 of the initial charging current and continue charging until the electrolyte releases intense bubbles, and both the specific gravity and voltage remain stable for 3 consecutive hours. 2. Charging Time: The total charging time is approximately 45-65 hours, with the temperature controlled between 35-40°C. After the initial charging is completed, if the specific gravity of the electrolyte does not meet the specified requirements, use distilled water or electrolyte with a specific gravity of 1.4 for adjustment. After adjustment, charge for another 2 hours until the specific gravity meets the specified requirements.

It resembles a handle-like switch; pull it up to adjust the steering wheel, and push it back down to lock it in place once the desired position is set. Related details are as follows: 1. Criteria for Correct Steering Wheel Adjustment: The steering wheel should not obstruct the view of the instrument panel. When holding the steering wheel at the 9 o'clock and 3 o'clock positions with arms fully extended, the arms should be parallel to the ground. 2. Influencing Factors: The steering wheel, seat, and pedals are the main components affecting driving posture. As the most critical factor, the steering wheel is irreplaceable in terms of safety. Most modern vehicles support vertical adjustment of the steering wheel, meeting the needs of the vast majority of drivers.
