1. RULES OF THE
ROAD

2. Rules of the road
 Rules of the road and driving etiquette are
the general practices and procedures that road
users are required to follow. These rules
usually apply to all road users, though they are
of special importance to motorists and cyclists.
These rules govern interactions between
vehicles and with pedestrians.

3. Rules
 As a general rule, drivers are expected to avoid a
collision with another vehicle and pedestrians,
regardless of whether or not the applicable rules
of the road allow them to be where they happen to
be.
 In addition to the rules applicable by default, traffic
signs and traffic lights must be obeyed, and
instructions may be given by a police officer,
either routinely (on a busy crossing instead of
traffic lights) or as road traffic control around a
construction zone, accident, or other road
disruption.

5. Traffic regulations
 In many countries, the rules of the road are codified, setting out
the legal requirements and punishments for breaking them.
 In the United Kingdom, the rules are set out in the Highway
Code, which includes obligations but also advice on how to
drive sensibly and safely.
 In the United States, traffic laws are regulated by the states
and municipalities through their respective traffic codes. Most
of these are based at least in part on the Uniform Vehicle
Code, but there are variations from state to state. In states
such as Florida, traffic law and criminal law are separate,
therefore, unless someone flees a scene of an accident,
commits vehicular homicide or manslaughter, they are only
guilty of a minor traffic offense. However, states such as South
Carolina have completely criminalized their traffic law, so, for
example, you are guilty of a misdemeanor simply for travelling
5 miles over the speed limit.

6. Rules in other countries
 Not all countries are signatory to the
convention and, even among signatories, local
variations in practice may be found. There are
also unwritten local rules of the road, which
are generally understood by local drivers.

7. Rules in Mexico
 In towns:40 km/h
 On highways:80 km/h
 On motorways:110 km/h
 Right-hand driving/left-hand driving:Right-hand traffic
 Alcohol:80 mg/100 mL
 Seat belt mandatory:yes
 Mobile phone:Only hands-free telephones may be used.
 Toll fees:There are usage fees for some motorways (called
cuota).S
 pecific rules of the counry:Petrol: magna sin and premium
(lead free)
Every car (even hired cars) is prohibited in Mexico City one
day per week (identified by number plate).
Speed humps are often used to enforce speed limits.

8. Road traffic safety
 Road traffic safety refers to methods
and measures for reducing the risk of a
person using the road network being
killed or seriously injured. The users of a
road
include pedestrians, cyclists, motorists,
their passengers, and passengers of on-
road public transport, mainly buses and
trams. Best-practice road safety
strategies focus upon the prevention of
serious injury and death crashes in spite
of human fallibility(which is contrasted
with the old road safety paradigm of
simply reducing crashes assuming road
user compliance with traffic regulations).
Safe road design is now about providing
a road environment which ensures
vehicle speeds will be within the human
tolerances for serious injury and death
wherever conflict points exist.

9. Vehicle safety
 Cars
 Main article: Automobile safety
 Simulated crashes using crash test dummies can help improve
automobile design
 Safety can be improved by reducing the chances of a driver making an
error, or by designing vehicles to reduce the severity of crashes that do
occur. Most industrialized countries have comprehensive requirements
and specifications for safety-related vehicle
devices, systems, design, and construction. These may include:
 Passenger restraints such as seat belts— often in conjunction
with laws requiring their use— and airbags
 Crash avoidance equipment such as lights and reflectors
 Driver assistance systems such as Electronic Stability Control
 Crash survivability design including fire-retardant interior
materials, standards for fuel system integrity, and the use of safety
glass
 Sobriety detectors: These interlocks prevent the ignition key from
working if the driver breathes into one and it detects significant
quantities of alcohol. They have been used by some commercial
