Further documentation
The documents below were produced in December 2003 - although there have been minor changes to the descriptions/labels of a few variables/codes there have been no changes to the variables or the valid codes.
variable 2.9 Vehicle location at time of accident...
the check "IF 1.12 (1st Road Class) = 1 or 2.." should be:
IF 1.12 (1st Road Class) = 1 or 2 THEN 2.9 = 00, 02, 05, 06, 07 or 08
because code 02 (bus lane) is valid (as there is one on part of the M4)
Variable 3.10 Pedestrian Location
the check "IF 3.10 = 01-04..." should be:
IF 3.10 = 01-04 THEN 1.20a (Pedestrian Crossing - Human Control) = 1 or 2 OR 1.20b (Pedestrian Crossing - Physical Facilities) = 1, 4, 5, 7, 8 or 9
because 1.20b code 7 "Footbridge or subway" is valid (it is a type of pedestrian crossing facility, which variable 3.10 codes 01-04 indicate is present).
Variable 2.22 Age of Driver
under the "Comments" heading, the check "If driver age unknown...." should be:
If Driver Age is unknown 2.22 MUST = BLANK (not 00 or 99)
BLANK acceptable if 2.24 (Hit and Run) = 1 or 2 or 2.7 (Manoeuvres) = 2
