It saddens me to read that yet another accident has happened on the road shoulder (Motorcycles topple, riders hurled 'as van crashes into them'; March 12).

I appeal to the authorities to review the designation of the road shoulder, especially along expressways, where motor vehicles are driven at high speed.

Is the marking on the road clear enough to indicate that the stretch is a shoulder? I believe there is no indication apart from a continuous white line, which could cause drivers to mistake it for another lane.

Perhaps stripes in different colours, such as yellow or red, could be drawn at short regular intervals.

Road shoulders are meant for emergency vehicles to use if the roads are congested. But what is there to stop ordinary vehicles from using them too?

Is the rule enforced? Are errant drivers caught and penalised, and such incidents publicised?

The nine motorcyclists who were knocked down were taking shelter from the rain.

Was the spot a rain shelter? Perhaps there needs to be more protection from careless drivers who swerve into this lane.
