D. General: Requirements of similar iaws in ten other states have been reviewed before suggesting the following formula as a guide in checking flaps. Several of those states have provisions requiring tang_ent-angles ranging from 10 degrees to 221 degrees and one requires all flaps extend to within 6 inches of the roadway. Therefore, it appears that the provisions of Vehicle Code Section 678.5 will be satisfactorily complied with by the use of a 20 degree tangent-angle, when vehicle is unloaded.. '' '51

E. Formula:

Tohlcls Unloafletl helght (tn tnctroE) '= .36 x dlatance (ln tnchea)

1. The above formula is a method of establishing the 20 degree tangent-angle in relation to a vehicle.

F. Enforcement:

1. If the body of a vehicle, or attachments thereto, are not sufficient to efiectively minimize the spray or splash of water or mud to the rear, then fenders, flaps, and/or other devices shall at all times be in place.

2. Flaps should be sufficiently rigid to prevent them from swaying above the 20 degree tangent-angle when the vehicle is in motion.

3. Flaps, alone, may not be sufficient in all cases' Bodies of many trucks, trailers, and other vehicles do not afiord adequate protection against the spray of water to the rear, and a fender extending at least to the top-center of the rvheel is necessary in addition to flaPs.

1. Fenders, covers, and/or other devices may also be required on the front rvheels of trailers and other vehicles rvhere the overhang of the sides of the body is not sufficient to effectively minimize the spray or splash of water or mud to the rear of vehicle."

A general discussion of the difficulties involved in the application of the Order as regards !.ogging and lumber trucks and trailers ensued.

The conclusion can be well summed up by repeating in a few words the gist of Captain Douarin's lengthy remarks to the effect that a problem was created in the passage of the law by the Legislature. The problem is to "effectively minimize the spray or splash of water or mud to the rear of the vehicle." The remedy is not spelled out in the law. The ansrver is not up to the Highway Patrol. Compliance is t*re..function of the Patrol. The answer is up to the operalors .bf the vehicles.

It was,(uite evident that, in the opinion of the Patrol, compliance requires the covering of wheels, either by the truck body or by fenders and in addition, the use of an apron or mud flap where necessary, all of which must be in place rvhen the vehicle is on a public highway.

Compliance on logging trucks was described to present the greatest difficulty. Captain Douarin reported the problem had been solved on logging trucks operating in Oregon and agreed to furnish to this office a picture of such an equipped logging truck,'copies of which we agreed to distribute to the members of the Association' as soon as picture is available.
