2. A vehicle for transporting prisoners which does not have doors in the prison compartment that can be opened from the inside, has no alternative exit that can be operated by an authorised person in an emergency.
3. A hinge for a door or other hinged panel is not securely attached to both the vehicle body and to the door or other hinged panel due to loose connections, corrosion or other damage (Note 1).
4. A latch, catch, striker or any other part of a door or hinged panel retention system is not securely attached, or is in poor condition, due to a loose connection, corrosion or other damage (Note 1).
5. A door used for entrance and exit of the driver or passengers cannot be opened from the inside, unless the vehicle is designed or adapted to transport prisoners and the door is inoperable from the inside of the prison compartment.
6. A child safety lock or similar safety device cannot be deactivated.
7. There is corrosion damage within 150 mm of the hinge of a door or other hinged panel (see Figure 6-1-1).
8. There is corrosion damage within 150 mm of the latch of a door or other hinged panel (see Figure 6-1-1).
8. A door used for entrance and exit of the driver or passengers does not open or close easily.
10. A door or other hinged panel does not remain secure in a closed or locked position.
11. A modification (Note 2) affects door or hinged panel retention systems, and:
a) is not excluded from the requirements for LVV specialist certification (Table 6-1-1), and
b) is missing proof of LVV specialist or accepted overseas certification, ie:
i. the vehicle is not fitted with a valid LVV certification plate, or
ii. the operator is not able to produce a valid modification declaration or authority card, or
iii. the vehicle has not been certified to an accepted overseas system as described in Technical bulletin 13.
Corrosion damage is where the metal has been eaten away, which is evident by pitting. The outward signs of such corrosion damage is typically displayed by the lifting or bubbling of paint. In extreme cases, the area affected by the corrosion damage will fall out and leave a hole.
