How Many Class Hours Are Required for Subject Two?

Subject Two requires a total of 24 class hours, including 2 hours of theoretical instruction and 22 hours of practical training. Below are the key points to note for the Subject Two test: Reverse Parking: The main deductions in reverse parking include driving over the line, failing to enter the parking space, exceeding the time limit, and not following the designated route. After the new regulations, reverse parking now has a time limit of 210 seconds; exceeding this time results in a failed test. During the test, you must first reverse into the right parking space, then the left one. Not following this sequence will result in a failed test. Pay attention to maintaining a 30cm margin from the side. Parallel Parking: The main deductions in parallel parking involve the turn signal, maintaining a 30cm margin, and driving over the line. When entering the test area, steer right in advance and align the highest point of the windshield wiper with the roadside line to adjust the 30cm margin. During the reverse, remember the first right full lock, straightening, left full lock, parking in the space, and turning on the left turn signal. When exiting, observe the rearview mirror to prevent the wheels from driving over the line on either side. 90-Degree Turn: The main deductions in the 90-degree turn involve the turn signal and driving over the line. After entering the test area, turn on the turn signal and turn it off after the voice prompt. Incorrect operation of the turn signal will result in a 10-point deduction. After entering the 90-degree turn, adjust the vehicle to maintain a 30cm margin from the side line, similar to parallel parking. When executing the full lock, slightly release the clutch to prevent stalling or stopping midway. Straighten the vehicle only after the rear wheels exit the turn to prevent

What are the black and yellow road signs on the road?

The yellow and black curb markings are road construction safety signs in traffic signs, also known as road barrier signs. One function of the yellow and black curb markings is to warn and remind. Generally, solvent-based paint is used, which is air-drying. The yellow and black effect is achieved through a "color overlay" method—first spraying the main color, such as yellow, then covering it with a template or other regular striped stencil before spraying black. Below is an introduction to the basic meanings of traffic sign colors under normal circumstances: 1. Red: Indicates prohibition, stop, or danger, used for the borders, background, or slashes of prohibition signs, as well as for cross symbols, slash symbols, and the background of warning linear guide signs. 2. Yellow or fluorescent yellow: Indicates a warning, used for the background of warning signs. 3. Blue: Indicates instructions or compliance, used for the background of directional signs; indicates driving information such as place names, routes, or directions, used for the background of general road guide signs. 4. Green: Indicates driving information such as place names, routes, or directions, used for the background of highway and urban expressway guide signs.

How to Open the Camry Hood?

Method to open the Camry hood: There is a "release lever" near the front of your left knee. Pull it, and the hood will pop open slightly. Then, reach under the front center of the hood and lift it to fully open. The Camry is a model under GAC Toyota, with body dimensions of 4900mm in length, 1840mm in width, and 1455mm in height, and a wheelbase of 2825mm. In terms of appearance, the Camry features dual design styles: Luxury and Sport. The Luxury version adopts a large trapezoidal horizontal grille, with a streamlined body posture, lower waistline, and an extended roofline that increases rear headroom. The Sport version features a three-layer grille front face, debuts with a two-tone body and "all-black" cabin design, and adopts a dual-side quad-exhaust pipe layout at the rear.

What is the difference between DOT4 and DOT5.1?

Different compositions. Here are the specific introductions: 1. DOT4: Generally ester-based: The ester type adds a large amount of borate ester on the basis of the alcohol ether type. Borate ester is formed by the esterification reaction of low-polyethylene glycol or propylene glycol with boric acid. The boiling point of borate ester is higher than that of low-polyethylene glycol or propylene glycol, so its braking performance is better. Borate ester also has strong moisture resistance, which can decompose the absorbed water, thereby slowing down the boiling point drop caused by water absorption. Therefore, the ester type performs better than the alcohol ether type, and the price is also higher. 2. DOT5.1: Generally silicone-based: It is refined from high-cost silicone base oil, with strong high-temperature resistance and water absorption resistance, and can withstand relatively strong conditions. However, DOT5.1 is generally used for professional racing or military purposes, and is basically not available on the market, so it can be ignored.

Will passengers in the back seat of a sedan be penalized for not wearing seat belts?

Passengers in the back seat of a car will be fined for not wearing seat belts. The traffic police department requires all passengers in vehicles to fasten their seat belts as required. If violated, the traffic police will impose a fine on the driver and deduct 2 points; if passengers do not use seat belts as required, the driver will be fined without point deduction. Below are specific details about car seat belts: 1. Ensuring passenger safety: Car seat belts can protect passengers' safety, especially on highways where rear passengers need to wear seat belts. A seat belt buckle is a device that can be inserted into the car's seat belt socket, preventing the seat belt alarm from sounding when the driver does not fasten the seat belt. 2. Ensuring driving safety: Seat belts are the only guarantee of driving safety for drivers and are an active safety measure. Even when driving at relatively low speeds, in the event of a collision or emergency braking, the resulting inertia, though relatively small, is still enough to cause the driver and passengers to lose control of their bodies, potentially colliding with hard components such as the steering wheel or windshield, resulting in bodily harm.

Is Cleaning an Oxygen Sensor Effective?

Whether cleaning an oxygen sensor is effective depends on the situation. If the tip of the oxygen sensor is found to be black (mainly due to carbon deposits), cleaning it can be very useful at this time. However, if the tip is white or brown, it indicates that the oxygen sensor has been poisoned. No matter what type of poisoning the oxygen sensor has, cleaning it multiple times will not help, and it needs to be replaced promptly. In engines using a three-way catalytic converter to reduce exhaust pollution, the oxygen sensor is an indispensable component. Since the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, the three-way catalyst's purification ability for CO, HC, and NOx will sharply decrease. Therefore, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust and send a feedback signal to the ECU. The ECU then controls the increase or decrease of the fuel injector's fuel injection amount, thereby keeping the air-fuel ratio of the mixture near the theoretical value.
