Good question

Hello Prof Wong

Are any of these what you were looking for?

Measuring Cognitive Distraction in the Automobile Fact Sheet

https://www.aaafoundation.org/sites/default/files/MeasuringCognitiveDistractionFS.pdf

This is a test from Quebec:

https://saaq.gouv.qc.ca/fileadmin/documents/publications/disctracted-driver-test.pdf

I found this UK site when adding music to my search, but it looks as if it is due to being refreshed:

This Brodsky & Slor (2013) paper was referenced on this webpage that was previous to the above:

I haven't seen the full text to this paper by Anderson et al (2012) but there could be a test mentioned? Or perhaps the author (on ResearchGate) would know of one:

Article Review of Driving with music: Cognitive-behavioural implications.

Hello Dr. Mary, thank you very much for your message and I will read the articles carefully. Here I also hoe to know what kind of variables can be used to measure driver's distraction in driving.

I would think that a driving simulation task would give you the best experimental control over potential distractions, e.g,, a smartphone buzzing or pinging in the seat next to the driver. 

I would think that would be much more effective than using questionnaires or other indirect measures of the effect of distractions. 

Here's a link to a study I found that used driving simulation to look at the effects of talking on a mobile phone.
