I support Mr Seah Yam Meng's call (Make it illegal to smoke in vehicles; March 14).

It is not uncommon to see drivers lighting up in their vehicles, with one hand on the wheel and the other holding a cigarette and flicking ash out of the window.

Not only does this amount to littering, but it is also a possible cause of inattention while driving.

A split second of inattention at the wheel can cause the death of an innocent person.

Smoking while driving ought to be treated like using a mobile device while driving.

I also hope that the restrictions on the purchase, use and possession of tobacco products by under-21s can be put in place as soon as possible, instead of in stages (Minimum legal age for smoking to be raised to 21; March 10).

Let us all work together to make our roads safer and our environment healthier for all.
