The 2.31 sign indicates that you must not drive below the speed shown on the sign. It sets a mandatory lower limit for your speed. You are allowed to drive at that speed or faster, provided it is safe and legal.
You must ensure you are already driving at or above the indicated minimum speed *before* you pass the sign. The instruction takes effect from the point where the sign is placed.
The minimum speed limit remains in effect until you pass a sign that cancels it, such as an 'End of all restrictions' sign, or until a new speed limit instruction is given. Always be observant of subsequent signs and road markings.
Yes, you are permitted to drive slower than the indicated minimum speed if traffic conditions, road hazards, or other traffic rules necessitate it. For example, if there is heavy traffic, poor visibility, or you are approaching a pedestrian crossing, you should adjust your speed accordingly, even if it's below the stated minimum.
A common trap is assuming the minimum speed applies only when the road is clear. Learners might also forget that the restriction continues until explicitly ended, or they might not understand they need to prepare their speed before the sign itself. Always read supplementary panels or arrows that might specify the rule applies only to certain lanes or vehicle types.
