While Forum members are looking for their phone policies, here is an earlier thread which could be of relevance.

Flick me an email Safetyatcablepricedotcodotnz

Thank you Peter.

Thank you Michael, I have emailed you.

This is not answering your request Shirley, but it is still related.

An internal article I wrote a few years ago about the question if hands free talking is safe.

The short answer - it is no safer than a drunk driver behind the wheel

Best policy is driver's phones off in moving vehicles. 2nd best is use hands free to ascertain whether its a quick response required and if not pull over to complete the call

Consider why policies are required and how wide or narrow the scope is. The objective is important.
Consider also what is wanted and what is needed. Are they identical.

Thank you for the contribution Paul

Thank you for your contribution Keith

I'd second KeithH in asking what they're trying to achieve by adding a policy.
Allow me to be contrary.
Any distractions are detrimental to driving concentration. Changing radio channel, adjusting temperature, eating, drinking, talking with passengers etc. all distract from the primary task of keeping the vehicle on the road. Should we have policies for those?
And then the "No pressure to answer when the boss is calling - the boss will not get grumpy" policy?
I'd flip my response around and ask how ShopCare is helping their drivers be as competent as they can be. Do they put them through Defensive Driving courses, or practical courses, where they can learn far more holistically?

Thank you for your input Jan-Ulf
