Proposal to clarify the provisions on the extended field of vision on heavy goods vehicles across different mirror classes. The text would require assessment of normal and extended fields of vision using a single mirror adjustment and to allow for the loss of up to 10% of the close-proximity field of vision in such configurations. The proposal would also clarify the transitional provisions and provisions for aftermarket devices.
