Test Details

Driving Field Test
Jurisdiction
Licence Class

Use Commercial for the Austroads commercial medical standard, including MR/HR/HC/MC heavy vehicle work, public-passenger authorities, dangerous goods, and related accreditation.

Vision Status

Test Reliability

Record the reliability values printed on the visual-field report. They decide whether the field is usable before the driving rules are applied.

No reliability warning from entered values
Reliable if ≤ 20%
%

Enter the false-positive value from the source test rather than choosing a preference. A false positive means the patient responded when no stimulus was presented. Above 20% makes standard Esterman evidence unreliable and should trigger repeat testing or manual review.

Fixation monitoring recorded

Monitored and recorded

Record whether fixation monitoring was performed and documented on the source test.

About this tool & limitationsRead once before clinical use

Decision support only

The driver licensing authority makes the final licensing decision. This tool helps a clinician apply Austroads rules deterministically; it does not replace clinical judgment.

Not a TGA-listed medical device

DRIVE App is not a registered or certified medical device. The clinician remains responsible for the final assessment and any report sent to the licensing authority.

Your data stays on your device

Every assessment runs entirely in your browser. No grid points, patient information, or test details are sent to any server.

Manual entry only

Image upload and automatic parsing are not part of this version. Mark missed points by hand against the source printout.

Do not enter patient identifiers

The diagnosis and free-text fields are not encrypted at rest in your browser. Do not enter names, Medicare numbers, dates of birth, or any other identifying details.
