Traffic control signals are placed at intersections in other to keep traffic moving and to also avoid a crash.
In Nigeria most people ignored the traffic control but it shouldn't be
so. Drivers, pedestrians, and bicycle riders must obey these signals,
except when a road safety official is directing traffic.
Stop on the stop line if your car is nearest the signal.
Some signals change only when a car is at the stop line. Occasionally,
even when properly positioned near the stop bar, motorcyclists and
bicyclists may not be detected.
Red
Come to a complete stop at the marked stop line or before moving into
the cross-walk or intersection. At most intersections, after stopping,
you may turn right on red if the
way is clear. Some intersections display a "NO TURN ON RED" sign, which
you must obey. Left turns on a red light from a one-way street into a
one-way street are also allowed.
Anyone convicted of running a red light is required to complete a basic driver improvement course.
Yellow
Stop if you can safely do so. The light will soon be red, so get ready to stop any time soon.
Green
Go - but only if the intersection is clear. Yield to pedestrians and vehicles still in the intersection.
If turning left, wait for a gap in oncoming traffic to complete a turn.
If you turn left or right, yield to pedestrians crossing in the
cross-walk that you turn into.
Pedestrian signals show words or
pictures similar to the following examples: "WALK" or "Walking Person" lights mean a pedestrian may begin crossing the street.
"DON'T WALK" or "Raised Hand" lights mean a pedestrian may not begin
crossing. A pedestrian in the cross-walk when the "DON'T WALK" or
"Raised Hand" signal begins flashing should finish crossing the street.
Red Arrow
Just like a red light, come to a complete stop at the marked stop line
or before moving into the cross-walk or intersection. After stopping,
you may turn right on a red arrow at most intersections if the way is
clear. Some intersections display a "NO TURN ON RED" sign, which you
must obey. Left turns on a red arrow from a one-way street into a
one-way street are also allowed.
Yellow Arrow
Stop if you can. The light will soon be red. The yellow arrow means the
same as the yellow light, but applies only to movement in the direction
of the arrow.
Flashing Yellow Arrow
A flashing yellow arrow means left turns are allowed. Yield to oncoming
traffic and pedestrians. The oncoming traffic has a green light.
Green Arrow
A green arrow, pointing right or left, means you may make a turn in the
direction of the arrow. If the red light is burning at the same time,
you must be in the proper lane for such a turn and you must yield the
right-of-way to vehicles and pedestrians clearing the intersection.
Flashing Signals
A flashing red light means the same thing as a stop sign. It is used at dangerous intersections.
A flashing yellow light means you may move forward with caution. It is
used at, or just before, dangerous intersections, or to alert you to a
warning sign such as a school crossing or sharp curve
