Comprehensive Guide to Traffic Law and Road Safety

General Vehicle Laws and Driving Procedures

When operating a vehicle, specific legal requirements must be followed to ensure the safety of all road users. When entering a tunnel during daytime, drivers are required to turn on their regular low beam headlights and reduce their speed. Similarly, at night, when driving behind another vehicle, a driver must use the normal low beam headlights rather than high beams to avoid blinding the driver in front. If an oncoming vehicle approaches from the opposite direction with its high beams on, the driver should immediately switch to normal low beam headlights. When refueling at a gas station, it is a legal requirement to turn off the car engine to prevent fire hazards. Before even starting the engine, a driver is expected to perform a routine check of various vehicle systems daily. Once inside the vehicle, the specific order of preparations should be: first, adjust the seat; second, adjust the mirrors; and third, fasten the seat belt. Seat belts must be fastened by the driver and all passengers prior to setting off. The head rest in a vehicle is specifically designed to protect the neck during a rear-end collision and should not be used as a sleeping pillow. Additionally, before stepping into a vehicle, a driver should look around and under the vehicle to ensure the path is clear.

Intersection Safety and Traffic Management

Safety at intersections involves adhering to a hierarchy of traffic control. If an intersection is regulated simultaneously by a traffic policeman, active traffic lights, and fixed signs, the driver must prioritize and follow the traffic policeman’s instructions above all others. If a traffic light turns yellow while a vehicle is already inside the intersection, the driver should continue forward cautiously rather than stopping abruptly. At intersections featuring a flashing yellow light, the driver should reduce speed and proceed with caution, providing the right of way where necessary. If traffic lights are entirely non-functional, the driver should treat the location as an intersection without traffic lights. When turning right at a green light, mirrors and blind spots must be checked, and the driver must give way to pedestrians. On traditional four-way intersections, the vehicle that has already entered the intersection has the right of way, or generally, the vehicle that arrived first. In situations where two drivers approach an intersection from opposite directions, the driver coming from the left should yield the right of way to the driver on the right.

Heavy Vehicle Operations and Trailer Coupling

Operating heavy vehicles requires specialized knowledge due to their size and mechanical differences. A heavy vehicle driver has significantly more blind spots than a standard car, typically at least four. Drivers must pay special attention to vehicle height when driving under bridges or into tunnels, and to vehicle width when overtaking. When turning right, a heavy vehicle driver must allow enough distance to the right side to prevent the rear wheels from skidding off the road or hitting curbs. Conversely, for left-hand turns, the driver must ensure the rear left wheels do not cross the center line.

When coupling a trailer to a tractor, the driver should reverse slowly below the trailer. After coupling, it is vital to ensure that both the air pipes and electric lines are properly connected. The trailer brake must be applied, and the legs must be lowered to the ground during the coupling process. When uncoupling, the driver must select a location with a plane area and solid ground; they must apply the trailer brake firmly and lower the legs to their maximum extension. On hills, heavy vehicle drivers should use an appropriate low gear to maintain control during descents, avoiding continuous use of main brakes which causes heat build-up and brake failure. If a driver fails to downshift before a descent and the vehicle gains too much speed, it may become impossible to change to a lower gear. On long uphill climbs, drivers should keep to the extreme right to allow smaller vehicles to pass and avoid engine pressure build-up.

Motorcycle Equipment and Handling

Motorcyclists must use specific protective gear to mitigate the risks of driving. A helmet is essential to prevent fatal head injuries and must be worn properly, as carrying it without wearing it offers no legal protection. A protective leather suit is used to resist friction with asphalt, while gloves and boots protect the extremities from cold, water, and injuries. Spine protective suits are designed to shield the spinal cord from injury, and eye glasses protect against wind, sand, and insects.

To maintain control of the motorcycle, the driver should sit close to the steering grips and hold them in a way that the right wrist is downwards to avoid unintended speed increases. The most effective braking occurs when using both the front and back brakes simultaneously while the motorcycle is moving in a straight line. If a motorcycle vibrates during motion, it is often caused by the uneven rotation of at least one wheel or tire. At night, motorcyclists are legally advised to wear fluorescent suits and attach luminous stripes to be visible. When being overtaken by a motorcycle, car drivers should allow the motorbike to use the entire width of the lane. When a car is overtaking a motorbike, a side distance of no less than $70\,cm$ must be maintained, whereas a distance of $60\,cm$ is required when overtaking another car.

Eco-Friendly Driving and Vehicle Maintenance

Eco-friendly driving is defined as the efficient use of fuel through smart and socially responsible practices that reduce air pollution and fuel consumption. Savings can reach up to $50\%$ in fuel and money, along with lower maintenance costs. The optimal speed range for eco-driving is $80\,km/h$ to $100\,km/h$. Drivers should monitor their speed on highways using cruise control and avoid exceeding a maximum engine speed of $2000\,RPM$, as exceeding this level significantly increases fuel consumption.

Vehicle maintenance is crucial for efficiency: regularly changing oil and filters can reduce fuel consumption by $1\%$ to $3\%$. Energy-conserving oils with friction-reducing additives are recommended. Air filters should be cleaned to improve engine performance by $6\%$ to $11\%$. Tire pressure should be checked at least once a month to preserve low rolling resistance. Tires have a shelf life not exceeding $6$ years from the manufacturing date or until the thread thickness reaches $1.6\,mm$, whichever comes first. Additionally, using the air conditioner can increase fuel consumption by $0.1$ to $0.3$. To reduce this, drivers should park in the shade and travel light.

Road Markings and Right of Way Rules

Road markings dictate lane discipline and safety. A solid line or other lane separator must not be crossed. If a lane is marked with both a solid and a broken line, a driver may only change lanes if the broken line is on their side. White lines demarcate lanes going in the same direction, while yellow lines separate lanes moving in opposite directions. Pavements (sidewalks) are strictly for pedestrians, children's trolleys, and the disabled; they are not for parking or obstructions.

Right of way must be yielded to vehicles already in a roundabout, to school buses with flashing hazard lights, and to emergency vehicles like police cars, ambulances, or fire trucks signaling their approach. In steep descents, the right of way typically goes to the vehicle moving upwards. Inside cities, a safe following distance of $2\,seconds$ should be maintained. In heavy traffic, mirrors should be checked every $4$ to $8\,seconds$.

Legal Thresholds and Emergency Protocols

Driving under the influence of alcohol or drugs is strictly prohibited. For drivers who have held a license for more than three years, the blood alcohol limit is $0.5\,g/L$. However, for the first three years of licensure, the limit is $0\,g/L$. Using a cell phone while driving is a violation unless using a hands-free Bluetooth system. Where speed signs are absent, the default limits are $50\,km/h$ inside populated areas, $100\,km/h$ outside populated areas, and $120\,km/h$ on freeways.

In emergencies, such as a stuck gas pedal, the driver should turn off the engine without locking the steering wheel. If the brakes fail, the driver should quickly pump the brakes with high frequency. If a tire blows out, the driver should release the accelerator, keep the steering wheel straight, and pull off the road. Warning triangles must be placed at a distance of $30\,meters$ on normal roads and $50\,meters$ on freeways if a vehicle is stopped. If a driver causes an accident, they are legally required to stop and take care of the victim; fleeing the scene is a major violation. Driving licenses must be renewed every $10$ years up until the age of $50$.
