To ensure your safety and enjoyment during your May Day trip, Shandong Plank Auto Technology Co., Ltd., based on its professional off-road modification experience and travel trends, has compiled the following general suggestions for you, to help you enjoy your journey to the fullest:

I. Travel Planning and Road Condition Management

Peak-time Travel and Route Optimization

• Time Selection: The period of free highway passage during the May Day holiday is from 0:00 on May 1st to 24:00 on May 5th. It is recommended to avoid the peak departure hours (8-12 on May 1st) and the peak return hours (14-19 on May 5th). Choosing to depart in the early morning or at night, or traveling during the middle of the holiday (May 2-3) can reduce the probability of congestion by approximately 30%.

• Route planning: Use navigation apps (such as Gaode or Baidu Maps) to check real-time traffic conditions. Prioritize national highways, provincial roads or newly opened expressways, and avoid popular main roads. For example, if there is a congestion on the expressway, you can exit the station in advance and take local roads to plan a route avoiding traffic restrictions. Use the "Gaode Map for Truck Navigation" function to do this.

2. Weather and Road Condition Warning

• Weather Response: In the northern regions, the temperature will generally rise to 25-29℃ from May 1st to 3rd. Sun protection measures should be taken; in the southern regions, there may be moderate to heavy rain from May 4th to 5th. Please be cautious:

When driving in rainy weather, maintain a sufficient distance between vehicles (it is recommended to be 1.5 times that on dry roads), and avoid sudden braking to prevent skidding.

◦ Low-lying sections are prone to water accumulation. Proceed with caution to prevent engine water ingress.

• Warning Alert: Follow "China Weather Network" or the local meteorological department's official account to promptly receive alerts for thunderstorms and strong winds.

II. Vehicle Safety Inspection (Especially for Modified Vehicles)

Special inspection of modified components

• If the vehicle has undergone modifications such as raised chassis, strengthened suspension, or installation of off-road tires, special attention should be paid to the following checks:

Is the chassis screw properly tightened to prevent it from loosening due to off-road bumps?

Is there any abnormal wear or oil leakage at the connection points of the modified suspension system?

◦ Does the pressure of the off-road tires meet the requirements for unpaved roads (it is recommended to be 0.2-0.3 bar lower than the pressure of road tires), and the depth of the tread should be no less than 1.6 millimeters?

Carry emergency tools such as tow ropes and anti-skid chains to be ready for complex road conditions.

2. Routine Vehicle Maintenance

• Lights and Brakes: Check whether the high beam lights, fog lights, turn signals and brake lights are functioning properly, and whether the thickness of the brake pads is below the safety limit.

• Oil and Battery: Ensure that the engine oil, coolant, and windshield washer fluid are sufficient, and that the battery voltage is stable (a 12V battery should maintain a voltage between 12.4 and 12.6 volts).

•Wiper blades: Replace the worn-out rubber strips, test the wiper performance, and prevent obstructed vision during rain.

III. Precautions for Off-road Driving and Camping

Off-road road condition preparation

• If you plan to cross unpaved roads, it is recommended:

Download the offline map in advance and mark the dangerous sections (such as steep slopes and water-crossing points).

Carry tools such as shovels and jacks to deal with vehicle stalling situations.

Adhere to the "slow entry and fast exit" principle to prevent damage to the suspension system caused by rapid ascent of the slope.

2. Camping Equipment Inspection

• Tents and sleeping bags: Check if the tent stakes and windproof ropes are complete, and ensure that the sleeping bag's temperature rating matches the expected nighttime temperature at the destination.

• Cooking utensils and lighting: Carry portable stoves and tableware, ensure that the gas tanks are fully charged; equip with headlamps or solar tent lights to facilitate nighttime activities.

• Moisture-proof and Warmth-keeping: Use a moisture-proof pad to isolate the moisture from the ground, and prepare sufficient warm clothing to cope with the temperature variations in the mountainous area.

IV. Safety and Emergency Recommendations

Driving Safety

• Strictly prohibit driving while fatigued. Take a 15-minute break every 2 hours; slow down on mountainous sections and avoid overtaking at bends.

When driving at night, turn on the low beam headlights. When encountering an oncoming vehicle, switch your own lights to avoid dazzling the other driver.

2. Emergency Handling

If any abnormalities occur with the modified parts, you can promptly contact the installation store or call the free consultation number of Planck at 13336366030 for assistance.

There is a first-aid kit in the vehicle (containing band-aids, iodine tincture, bandages), a reflective vest and a triangular warning sign.

• In case of vehicle breakdown, please contact road rescue services (such as the national expressway rescue hotline 12122) first. Do not attempt to repair it on your own.

V. Civilized Travel and Epidemic Prevention Tips

Environment and Order

After the camping is over, make sure to remove all the garbage and protect the natural environment.

Inside the scenic area, abide by the capacity limit regulations, queue up orderly and avoid gathering in groups.

2. Health Protection

It is recommended to carry masks and disinfectant wipes with you. Wear them when entering indoor areas or crowded places.

Pay attention to the latest epidemic prevention policies of the destination. Some scenic spots may still require health code verification.

Special reminder: During the May Day holiday, Shandong Planck Automotive Technology Co., Ltd. will offer free consultation services. If you have any questions, please call 13336366030. Wish you a pleasant journey and a safe return home!
