How Many Questions Are There in the Motorcycle Theory Test (Subject 1)?

There are a total of 50 questions in the motorcycle theory test (Subject 1). Below are the specific details about the motorcycle test: Test Instructions: Before taking the test, the fingerprint of the right index finger must be recorded to prevent impersonation or proxy test-taking. The test duration is 45 minutes, with a total of 50 questions, which is 50 fewer than the C1 driver's license test. All questions are objective, with the first 20 being multiple-choice and the remaining 30 being true/false. The full score is 100, and a score of 90 or above is required to pass. Test-takers have two attempts. If they fail the first time, they can retake the test immediately. If they still fail, they must pay a retake fee (which includes two test attempts) and wait for the driving school to schedule the next test date.

Feeling of sluggishness and lack of power while driving; 4. Pungent exhaust fumes and excessive emissions; 5. Increased fuel consumption compared to before. Solutions for engine carbon deposits: 1. Using an engine carbon cleaning system ("drip cleaning"); 2. Machine cleaning; 3. Engine disassembly cleaning. Causes of engine carbon deposits: 1. Long-term poor driving habits by the owner; 2. Poor quality of gasoline used; 3. Aging or damaged carburetor in the engine. Methods for maintaining a car engine: 1. Regularly change the engine oil and filter; 2.

What is a Trailer?

A type of freight vehicle that lacks its own power and requires the pulling force of a tractor to move. Below are detailed explanations about trailers: 1. Definition: A tractor refers to a large truck that needs a separate cab to pull the cargo container behind it, where the cab can be detached from the container. 2. Classification: There are two types: semi-trailers and full trailers. A semi-trailer, like the Liberation trucks from the 1950s and 60s, has its own cargo container with an additional container attached at the rear, which could carry something like an artillery piece. A semi-trailer means the vehicle itself has a cargo container, but for convenience, an extra container is towed behind, and the rearmost container can be detached—such a vehicle is called a semi-trailer. A full trailer is when the rear cargo container can be detached and requires a tractor to pull it.

What are the reasons why a Honda car won't start?

Here are the possible reasons why a Honda XRV won't start: 1. Battery depletion: Symptoms: The starter motor begins to turn but lacks sufficient power (weak rotation), eventually making only clicking sounds without turning. Low winter temperatures or forgetting to turn off certain electrical devices can prevent the vehicle from starting, especially with long-term short-distance low-speed usage in winter when battery voltage drops below rated values, making normal starting and operation impossible. Emergency solution: If this occurs, call the service center for assistance, perform a jump-start from another vehicle, or temporarily start the engine, then be sure to take the vehicle to a service center for battery recharge. 2. Fuel flow obstruction: Symptoms: No fuel pressure in the engine supply line. This situation often occurs on extremely cold mornings due to long-term contamination of fuel lines. At extremely low temperatures, water mixing with debris can block fuel lines, resulting in failure to start. Emergency solution: Move the vehicle to a warmer environment, and it should start after a while; or thoroughly resolve the issue by cleaning the fuel system.

Why is there a noise when shifting gears in an automatic transmission?

When an automatic transmission car makes a buzzing noise during gear shifting, it is due to stubborn dirt and impurities inside the transmission, especially when these contaminants accumulate inside the valve body, forming blockages that prevent effective regulation of oil pressure, leading to abnormal noises. Below is relevant information: 1. Solution: To address the abnormal noise during gear shifting in an automatic transmission, it is necessary to remove the stubborn dirt and impurities inside the transmission and effectively control the transmission's operating temperature. This will thoroughly resolve the transmission issue and prevent its recurrence. 2. Automatic Transmission: An automatic transmission has a self-locking device and a locking mechanism. The self-locking device prevents the gear from disengaging or changing the selected gear due to vibrations while driving. The self-locking device mainly consists of a spring, steel ball, and groove. When the driver selects a gear, the spring in the self-locking device presses the steel ball into the groove, locking the gear in place to prevent unintended disengagement. When manually shifting gears with the gear lever, the steel ball forcibly compresses the spring and exits the groove. Once the desired gear is engaged, the steel ball is pushed back into the groove by the spring, producing a "click" sound.
