Traffic Signs, Signals and Road Markings
Read the family first, then the symbol
Every sign in the UAE belongs to a family, and the family tells you what kind of message to expect before you decode the picture. Red circles prohibit (no entry, no overtaking, speed limit, no parking). Red triangles warn of a hazard ahead. Blue circles command a positive action (turn left, keep right, minimum speed). Rectangles inform or guide. A yellow background means the sign is temporary - usually roadworks - and it overrides the permanent sign it replaces. Shape reinforces this: octagon = stop, inverted triangle = give way, circle = regulation, rectangle = information.
Signals
Steady red means stop behind the line. Amber means stop, unless you are so close that stopping would itself cause a collision. Green means proceed only if the way ahead is clear. A green arrow protects only the movement it shows - do not assume the rest of the junction is safe. A flashing amber at a pedestrian crossing means give way to anyone on or about to enter the crossing.
Markings
A solid centre line must not be crossed; a broken line may be crossed to overtake when it is safe and permitted. Never enter a yellow box junction unless your exit is clear. Stop lines, give-way lines and lane arrows on the approach tell you which lane to choose early.
Traps
Questions swap one element: a triangle showing children is a warning, not a prohibition; a blue circle with a number is a minimum speed; "no stopping" is stricter than "no parking".
Rule of thumb: ask three questions in order - colour, shape, symbol - and if two readings conflict, the more restrictive one applies. Worked example: a red-bordered triangle with a pedestrian symbol is a warning to expect people crossing; it does not give pedestrians or you any new right of way.
