Driving Advice

Safe driving: what you shouldn’t ignore when traveling on the highway.

Share
Highways are tempting. Wide lanes, a stable car, music playing, and the feeling that "now it’s just driving straight ahead.” Highway travel can be comfortable and efficient as long as safety is never overlooked. Driving on highways does not mean it’s less demanding. On the contrary, highways are environments where higher speeds make driver attention even more critical, and where small mistakes can have serious consequences.

Safe driving requires constant focus, respect for the rules, and conscious decisions throughout the entire trip. Especially on long journeys, where fatigue and routine can easily lower your guard. If you’re planning a long trip, this Guerin guide helps ensure safe driving from the moment you enter the highway until the final exit.

Highways: fast and comfortable, but not risk-free.

It’s true that highways offer good driving conditions: clear signage, well-maintained pavement, and no intersections or traffic lights. Still, higher speeds and constant traffic demand extra attention. A small error, a moment of distraction, a misjudged following distance, or speeding can have far greater consequences at highway speeds. That’s why safe driving starts before entering the highway or even before leaving home.

The basic principles of safe driving.

There are no magic formulas to eliminate road risks, but there are essential principles that make a real difference. Many are at the core of defensive driving, a driving style focused on anticipating hazards and reducing the likelihood of accidents. Adopting these habits is key for anyone who wants to be a responsible driver and ensure a safe trip for everyone on board.

Respect speed limits.

Speed limits exist for a reason. They are not suggestions or personal challenges. Driving within the posted limit helps you react more effectively to unexpected situations, maintain safe following distances, and reduce the risk of serious accidents for everyone sharing the road.

Pay attention to road signs.

Traffic signs, electronic message boards, and temporary warnings, such as construction zones or accidents, should always be respected. Ignoring alerts can lead to sudden maneuvers or dangerous situations. A good driver reads the road ahead and adapts accordingly.

Keep a safe following distance.

On the highway, tailgating won’t get you there any faster. A safe following distance gives you time to react calmly to sudden braking. The higher the speed, the greater that distance should be.

Avoid distractions while driving.

Cell phones remain one of the leading causes of driver distraction. A text, a playlist change, or a quick glance is enough to compromise safe driving. Set your GPS before starting the trip and avoid any interaction that takes your eyes off the road.

Always wear a seat belt.

It may seem obvious, but it bears repeating: seat belts are mandatory for all passengers and remain one of the most effective ways to prevent serious injuries in a crash.

Alcohol and safe driving don’t mix.

Not "just one drink,” not "I feel fine.” Any amount of alcohol affects reaction time and decision-making. When it comes to safe driving, the rule is simple: if you drink, don’t drive. Safe driving goes beyond knowing speed limits or keeping distance; it’s about adopting good practices throughout the entire trip. Explore the tips you shouldn’t ignore for a safe journey.

Long trips: fatigue is also a risk.


On long drives, fatigue builds up. Highway monotony can cause drowsiness and loss of concentration, even for experienced drivers.

To maintain safe driving:
  • Take regular breaks (ideally every two hours).
  • Stay hydrated and avoid heavy meals.
  • If you feel tired, pull over. Arriving later is always better than taking unnecessary risks.

Up-to-date documents: safety also means prevention.


Keeping your documents current is essential. A valid driver’s license, vehicle registration, and active insurance are required, not just on highways, but on any road trip. Being prepared helps avoid legal issues and unnecessary stress.
