**Sixth, Special Circumstances Driving Tips**
When driving in bad weather or poor road conditions, it's important to maintain a steady speed and handle the vehicle gently. Avoid sudden lane changes and do not overtake unless absolutely necessary. If you do decide to overtake, make sure you fully understand the road conditions and have a clear view of the path ahead. Use your headlights promptly to improve visibility. Be cautious about driving on roads that may be covered with snow or ice, especially if the road surface is unclear. When encountering snowdrifts, especially at night, slow down and give way to other vehicles—never try to rush.
When climbing hills, use a low gear to maintain control and avoid shifting gears mid-climb. On downhill slopes, never coast without engine braking, as this can lead to loss of control. For novice drivers, it’s best to follow the road rather than attempt steep overpasses. Try to avoid parking on inclines, as it can be difficult to restart the vehicle. If you must park on a downhill slope during snow, ensure there's enough space to maneuver when leaving.
It's also advisable to carry non-slip materials like triangular wood or sandbags. In case of skidding or loss of control, and if the mechanical brake fails, use the triangular wood to gradually slow down the vehicle. In extreme cases, it may be necessary to abandon the car, but never attempt to fuel uphill, as this can lead to serious accidents.
**Driving in Fog**
If visibility drops below 50 meters due to fog, turn on your fog lights, side lights, and hazard lights. Drive slowly at around 20 km/h, keeping close to the left edge of the road, near the boundary between the main lane and the overtaking lane. Avoid using the rightmost emergency lane unless absolutely necessary.
**Driving on Icy Roads**
Winter temperatures often cause bridges, interchanges, and areas with standing water to freeze. Although traffic police usually don’t close highways, they may allow free-flowing traffic to keep things moving. However, many accidents result from reckless driving. When driving on freeways in freezing conditions, pay attention to temporary signs and markings. As you approach a bridge, reduce speed and pass smoothly without braking on icy surfaces.
**Seventh, Emergency Lanes**
Emergency lanes are essential for safe driving. They typically include an approach lane, a safety lane, and service areas. Their primary purpose is to guide uncontrolled vehicles away from the main road and help them stop safely without causing further damage or injuries.
Emergency lanes are commonly found on high-risk roads. Unfortunately, some drivers confuse them with service lanes, leading to serious accidents. The safety lane is usually gravel, while the service lane is paved. Once you enter the safety lane, turn on your hazard lights and place a warning triangle 150 meters behind your vehicle. Leave the highway area immediately and alert authorities.
**Eighth, Common Driving Problems and Solutions**
- **Engine Won't Start**: Check the distributor, spark plugs, and high-voltage lines for moisture. Dry them if needed. If the spark plug is damaged, replace it. Also, check if the battery has sufficient charge.
- **Flat Tire**: A rear tire blowout may cause the back of the car to sway, but steering should remain manageable. Gently press the brakes to slow down. A front tire blowout can cause the car to pull to one side. Keep both hands on the wheel, release the accelerator, and let the vehicle slow down using engine resistance. Do not slam the brakes.
- **Brake Failure**: Steer carefully based on road conditions and speed. Shift to a lower gear quickly, and use the handbrake cautiously. Avoid locking the brake, as this can damage the transmission and reduce braking power.
- **Overheating Engine**: Don’t turn off the engine after parking. Let it run while the fan cools it down. Once cooled, cover the radiator cap with a cloth and slowly open it to avoid scalding. Only use distilled or soft water when refilling coolant to prevent scale buildup.
**Ninth, Avoid Fatigue Driving**
Fatigue is one of the most dangerous causes of accidents. Many drivers ignore the risks of long hours behind the wheel, even if they arrive safely. It’s important to take regular breaks. On long trips, consider alternating between highways and scenic routes to rest and enjoy the journey. If possible, drive in shifts with another person every two hours. If no one is available, stop when you feel tired—walk around or take a short nap before continuing.
**Tenth, Snow Parking Tips**
When parking in snowy conditions, avoid areas with standing water, as they can freeze and damage tires. If parking outdoors, don’t engage the handbrake, as it may freeze. Instead, shift manual cars into first or reverse, and use wedges for automatics. Avoid parking under trees where falling branches could damage your car. Lift windshield wipers after parking to prevent them from freezing to the glass.
Use dry towels to cover windows and headlights after parking. This makes it easier to remove snow the next day. After turning off the lights, wipe the headlight covers with a towel to prevent ice buildup. This helps maintain visibility and protects the lamps from damage.
Pressure Gauge
A hydraulic pressure gauge is a device used to measure the pressure of a hydraulic system. It consists of a dial or digital display that shows the pressure reading in units of force per unit area, such as pounds per square inch (psi) or bar.
The gauge is typically connected to the hydraulic system through a pressure port or a pressure transducer. When the hydraulic fluid flows through the system, it exerts a force on the gauge, which is then converted into a pressure reading on the display.
Hydraulic pressure gauges are commonly used in various industries and applications, such as automotive, manufacturing, construction, and aerospace. They are essential for monitoring the pressure levels in hydraulic systems to ensure proper functioning and prevent damage or failure.
Some hydraulic pressure gauges are designed for specific pressure ranges, while others are adjustable or have a wide range of measurement capabilities. They may also have additional features like maximum pressure indicators, peak hold functions, or digital interfaces for data logging.
Overall, hydraulic pressure gauges play a crucial role in maintaining the performance and safety of hydraulic systems by providing accurate pressure readings for troubleshooting, maintenance, and operational purposes.
