Overview
Long intercity trips differ from daily city driving in the strain they put on a car: hours of continuous highway-speed driving, changing temperatures, and often extra weight from luggage and passengers. A car not properly inspected before departure may reveal problems that stayed hidden during short daily drives, like a slow cooling system leak or unevenly worn tire. Proper pre-trip preparation reduces the chance of a mid-route breakdown and makes the journey safer and more comfortable for everyone aboard.
Key takeaways
- A slight steering wheel vibration at high speed not noticed at slower city speeds
- Skipping a pre-trip inspection and relying only on normal daily performance
- Check all fluid levels: engine oil, coolant, brake fluid, and power steering the day before the trip
- Follow the manufacturer's recommended value for full load, usually found on a sticker inside the driver's door, which may be slightly higher than the standard value for light daily driving.
Symptoms
- A slight steering wheel vibration at high speed not noticed at slower city speeds
- Higher-than-usual oil or coolant consumption after long distances
- Unusually hot brakes after descending long grades
- A warning light that only appears after hours of continuous driving
- Increased driver fatigue from poorly adjusted seats or suspension
Likely causes
- Skipping a pre-trip inspection and relying only on normal daily performance
- Tires with pressure or tread depth unsuitable for sustained highway speeds
- Ignoring a brake check before trips involving mountain roads or long descents
- Overloading (luggage and passengers) beyond the vehicle's recommended maximum
- Missing basic emergency gear in the car (spare tire, jack, jumper cables)
Diagnosis & repair steps
- Check all fluid levels: engine oil, coolant, brake fluid, and power steering the day before the trip
- Inspect all four tires plus the spare for pressure, tread depth, and sidewall damage
- Test brake performance and listen for any unusual squeal or vibration when applied
- Verify all exterior lights work (headlights, taillights, brake lights, turn signals)
- Distribute cargo weight evenly and don't exceed the maximum recommended in the owner's manual
- Prepare an emergency kit including jumper cables, a warning triangle, spare tire, and a first aid kit
- Plan rest breaks every two to three hours to reduce long-drive fatigue
Expected cost
A full pre-trip inspection at a certified shop typically costs SAR 100-250 ($27-67), covering fluids, tires, and brakes — a small amount compared to the cost of a sudden breakdown on a highway far from cities, which can involve towing and emergency repair exceeding SAR 1,000-2,500 ($270-670).

How to prevent it
Make a full inspection routine before any trip exceeding 300 km, keep an up-to-date maintenance log easy to review before travel, and avoid setting off on a long trip if the car has shown even a minor unusual symptom in the days beforehand.
FAQ
What tire pressure should be used for a long trip loaded with luggage?
Follow the manufacturer's recommended value for full load, usually found on a sticker inside the driver's door, which may be slightly higher than the standard value for light daily driving.
Should brakes be checked before every long trip even if relatively new?
Yes, especially if the trip includes mountain roads or long descents, since brakes experience much higher heat under these conditions compared to typical city driving.
How often should you stop for rest on a long trip?
It's recommended to stop every two to three hours for at least 15-20 minutes, not just for driver rest but also to quickly check tire condition and engine temperature.
What's the most important gear to have in the car for a long trip?
Jumper cables, a warning triangle and reflective vest, a functional spare tire and jack, a first aid kit, sufficient water, plus a backup phone charger that works from the car's power outlet.
