The Importance of Traffic Laws

Traffic laws are rules that regulate how people use the roads. They can range from very general rules like not driving over the speed limit to more specific ones such as not running red lights.


Generally speaking, traffic laws are enforced by local or state law enforcement agencies. There are also some national standards such as the UVC (Uniform Vehicle Code). Each of these laws has a different application and interpretation depending on the jurisdiction.

Speed limits

Every State has a basic speed law that requires drivers to operate their vehicles at a speed that is safe and reasonable under the conditions. However, it is difficult for drivers to determine what is the appropriate speed given the tr 인천운전연수 affic, roadway and weather conditions at any particular time. In order to provide guidance, each State has established a minimum statutory speed limit for most types of roads and a number of additional or optional speed limits for specific roadway segments. These posted or regulatory speed limits are sometimes called “speed zones” and are often set by an engineering study.

These speed studies usually consider the 85th percentile speed, which is the rate at which 85% of motorists are observed to travel on the road being studied, as well as other factors such as roadway design and crash experience. The goal is to set speed limits at levels that will achieve the desired level of safety without significantly affecting traffic flow or other roadway use, which can be achieved through roadway treatments and supportive enforcement (TRB, 1998).

When speed limits are lowered on residential roadways, compliance improves over 3 to 6 months after treatment. Unrealistic or unrealistic speed limits encourage people to disobey the basic speed law, which can increase accident risk for all road users including pedestrians. Families for Safe Streets supports a comprehensive speed limit setting program, in 인천운전연수 cluding enforcement, education and infrastructure changes to establish realistic and life-saving speed limits in New York City and throughout the State.


Proper road markings and traffic signs are important elements in improving perception of the road space, but their effectiveness relies on traffic participants receiving the information correctly. This is especially true for non-standard traffic signs, which can be used to signal the existence of hazards or unusual situations on the road. To improve the accuracy of these signals, it is necessary to study the relationship between them and personality traits of drivers.

A recent study examined the relationship between the comprehensibility of four different groups of traffic signs and the personal characteristics of 369 drivers. In the first step, the subjects were shown a sign and asked to evaluate its familiarity. They were also asked to indicate whether they understood the meaning of the sign. This procedure was repeated for the remaining three signs. The results showed that non-standard symbols and symbolic-text regulatory signs were better comprehended than standard traffic signs. The study also found that the comprehensibility of warning signs was lower than that of other types of traffic signs.

In addition, the study analyzed the influence of socio-demographic factors on the comprehensibility of the signs. It was found that the level of comprehensibility increased with age, driving experience and educational level. However, this effect was less pronounced for the groups of signs studied. In particular, higher comprehensibility of symbolic text and symbol-text regulatory signs was demonstrated by truck and emergency vehicle drivers. The comprehensibility of the group of warning signs was also enhanced by a driver profile with lower scores on all five personality factors.


Pedestrians are involved in many traffic accidents and often sustain serious injuries or death. This is why most states have laws regulating what pedestrians can and cannot do while crossing the street. Pedestrians should always look both ways before stepping off the curb. They should also never assume that the vehicle will stop for them.

According to state law, vehicles must yield the right-of-way to pedestrians crossing within a marked crosswalk or unmarked crosswalk at an intersection. Some states, like New Jersey, require that the vehicle must stop and wait for the pedestrian. While other states, such as Nebraska, only require that the vehicle yield when a pedestrian is located on their half of the road or within one lane of the vehicle.

It is also important to note that pedestrians are not allowed on limited-access roads, including expressway and interstate highways and their entrance and exit ramps. Whenever possible, pedestrians should walk on the sidewalks and, if not available, should walk facing traffic as far to the left side of the road as possible.

Pedestrians should also follow all pedestrian traffic signals. They should only cross the roadway at a controlled intersection during the “Walk” signal and should be careful when walking through roundabouts. Pedestrians should only cross from one “splitter island” to the next and should avoid crossing over to the center island of a roundabout. Pedestrians must also obey warning signs at at-grade railroad crossings and may not cross railroad tracks while trains are in operation.


Although laws vary from state to state, most include bicycles as vehicles and treat them similarly to motor vehicles in terms of traffic rules. The shared requirements of cars and bikes create structure and consistency for both users of the roadways, helping to prevent accidents and injuries.

A bicyclist must ride in a bike lane if one exists, or on a usable shoulder of the roadway when there is no bike lane. In either case, the cyclist must position themselves so they are visible to all drivers. They must also act predictably and be prepared to change lanes. Motor vehicles must give bicyclists 4 feet of clearance when passing them. Motor vehicles must not open their doors into the line of travel of a cyclist (dooring) unless it can be done safely with due care.

Bicyclists must signal turns and stops as motorists must, and they may use any through or turning lane that isn’t blocked by other vehicles. They must yield the right of way to pedestrians, and they should use a bell or other noise device to warn other road users of their presence when necessary.

Many cyclists do not follow traffic laws, putting them at risk of getting injured or injuring others. If you’re involved in a crash with a cyclist who didn’t obey the law, you could be partially at fault under New York comparative negligence laws.
