9.2 Green, Amber, Red and the Green Arrow

Green, amber, red and the green arrow

Layout tells you which lamp is which. Regulation 4 tells you what each circular means for a vehicle. Regulation 5 adds the green arrow. This section is independent study of those two regulations as printed in the GPF Theoretical Programme. Meaning questions are where the electronic paper separates a learner who can name the colours from a learner who can drive the junction.

Quick Answer: Green: you may pass the stop line and proceed, with due regard to other road users and subject to any police constable regulating traffic. Amber: you must not pass the stop line (or the signal, if the line is not visible), unless when amber first appears you are so close that you cannot safely stop. Red: you must not pass the stop line (or the signals if the line is not visible) until green is shown. A green arrow on black lets you proceed in the arrow’s direction while it is lit, even if the circular would otherwise require a stop.

Green is permission with duties, not a blank cheque

Regulation 4(a): the green signal indicates that vehicular traffic may pass the stop line and proceed with due regard to the safety of other users of the road and subject to the directions of any police constable who may be engaged in the regulation of traffic.

Three jobs sit in that one sentence:

1. May pass the stop line. On a steady green you are not required to halt at the line as if it were a STOP sign. You may go.
2. Due regard to other users. Green does not cancel pedestrians still clearing a crossing, a vehicle finishing a turn, a cyclist in your path, or a hire car that entered on the previous phase. The Road Traffic Code tells foot passengers at a traffic-light intersection to cross on the Green Light or the WALK signal only; your green still requires you to look for the person who started late or who is on the crossing when your phase begins. Regulation 189 (crossings) separately requires you to allow free passage to a foot passenger who has already started at a police-controlled intersection before you receive the signal to proceed. The same courtesy belongs at a signal head: people already on the carriageway are “other users of the road.”
3. Subject to a police constable. If a constable is engaged in the regulation of traffic, that constable’s directions bind you even on green. The circular does not outrank the officer. Chapter 7 covers emergency vehicles and police directions in the round; here the Light Signals Regulations themselves write the constable into the meaning of green. A GPF officer in the junction, a point-duty constable at a failed head, or an officer holding a stream for a procession is the regulation 4(a) constable. Do not treat green as a licence to drive around that person.

Green also does not authorise a left filter that the Code forbids. Code rule 50: when held up at a junction by Police or light signal, do not “Filter” to the left unless you receive a definite signal to do so. In left-hand traffic the near-side gap looks useful. Unless the circular green actually applies to your movement, or a green arrow (below) lights for that direction, or a constable definitely sends you, you stay.

The Theoretical Programme’s good-driving cluster still applies at a green: hold the vehicle on the handbrake at temporary stops such as traffic lights, then go through the learner start drill when the phase actually turns. Green is not an instruction to creep, roll, or ride the clutch across the line while you wait for a gap that the circular has already given you — or, worse, while the circular is still red.

Amber is a prohibition with one escape

Regulation 4(b): the amber light prohibits vehicular traffic from proceeding beyond the stop line, or, if the stop line is not for the time being visible, beyond the signal, except in the case of any vehicle which when the signal first appears is so close to the line or signals that it cannot safely be stopped before passing the line or signals.

Read amber as stop if you can do so safely. It is the change from green toward red. It is not a second green, not a “clear the junction at speed” colour, and not the same as flashing amber (section 9.3). The only named exception is already being so close, at the first appearance of amber, that a safe stop cannot be made before the line or the signal.

Exam swaps to refuse:

• Speed up so you beat the red. That is the opposite of a prohibition.
• Treat amber as advice with no legal bite. The regulation uses prohibiting.
• Use the exception because you prefer not to stop, or because the vehicle behind you is close. The test is whether you can safely stop, not whether stopping is inconvenient.
• Invent a “two-second rule” or a fixed distance the booklet does not print. The printed words are so close that you cannot safely be stopped.

If the stop line is not visible — worn paint after rain on an East Coast road, a flooded transverse, night glare, a vehicle already covering the mark — amber is read at the signal. You do not get a free pass because you cannot see the line. You treat the signal as the place beyond which you must not go, subject to the same cannot-safely-stop exception.

Red is a halt until green

Regulation 4(c): the red light prohibits vehicular traffic from proceeding beyond the stop line. If the line is not for the time being visible, beyond the signals, until the green light is shown.

Red is not a pause until you guess the phase is about to change. Red is not a pause until amber. Red is not a pause until the crossing looks empty. You wait until green is shown. If the line cannot be seen, you wait at the signals. Creeping over a faded line “because nobody is coming” is still a regulation 4(c) problem. So is treating a pedestrian WALK on a side face as your vehicular green.

The booklet sample that the traffic light controls all road users matters on red as well as on green. A cyclist, a motorcyclist, and a minibus share the same halt. Pedestrians should not be in the carriageway against DON’T WALK (section 9.3), but your red still means your vehicle does not occupy the crossing as a rolling queue. Regulation 189 also says you must not stop on a crossing unless you are prevented from proceeding or you must stop to avoid an accident. Halt behind the stop line (or at the signal), not on the stripes.

The green arrow on black

Regulation 5: a lamp which when lit shows a green arrow on a black background may be used in conjunction with the light signals. Where so used, vehicular traffic may proceed in the direction indicated by the arrow during such time as the arrow is illuminated, notwithstanding that such traffic would otherwise be required by the signal to stop.

Memorise the moving parts:

• The arrow is green on black, not a circular green with a painted pointer, and not a white arrow.
• It is used with the ordinary signals, not instead of knowing red, amber, and green.
• You may go only in the direction the arrow indicates. A left arrow is not a through-ahead permission. A right arrow is not a left filter.
• The permission lasts while the arrow is illuminated.
• It works even if the circular would otherwise require a stop. That is the whole point of the device: a named movement can run while other movements remain red.

Guyana is left-hand traffic, so a left green arrow (near side) is a common picture for a protected left while through traffic stays red. A right green arrow (off side) is a protected right across the opposite stream. The regulation does not lock the arrow to one side of the car. Teach the words: direction indicated by the arrow. Do not invent extra arrows the booklet does not describe (flashing arrows, amber arrows, or “any direction while any arrow is lit”).

The arrow is the definite signal that Code rule 50 was waiting for when it forbade a freelance left filter. If the arrow is dark and the circular is red, you are still required to stop. If the arrow is lit, you may take that direction with the same due regard to other users that green already demanded. An arrow is not a licence to hit a pedestrian who is still on the crossing, and it is still subject to a constable who is regulating the junction.

Meaning table for the three circulars and the arrow

Named Guyana roads still use this same meaning set. A signal on an East Bank restricted road, at Timehri, or on the approach to a town on the East Coast is not a different colour language. Bridges such as the Demerara Harbour Bridge and the Canje Bridge are Code speed-and-care locations; if a signal or a constable is controlling an approach, regulation 4 still supplies the meaning of the circulars.

Independent OpenExamPrep teaching of green, amber, red, and the arrow follows the printed regulations 4 and 5. It does not add extra colours, and it does not treat a police constable as optional decoration on a green.
