Opinion Per Curiam.
Jesse Sherman, doing business from Cheyenne, Wyoming, as Sherman Trailer Transportation, Inc., sought temporary authority pursuant to Section 210a of the Interstate Commerce Act1 to engage in the transportation of mobile homes in eight western states.2 Competing carriers protested, and the Motor Carrier Board of the Interstate Commerce Commission denied the request.3 On appeal, however, Division 1 of the Commission vacated the Board’s order and granted temporary authority restricted to secondary movement4 of mobile homes within the eight states.5 Barrett Mobile Home Transport, Inc., a competitor, invokes our review of that order, arguing that the Commission awarded the authority despite the absence of adequate supporting data, and thus acted arbitrarily and capriciously.
A motor carrier soliciting temporary operating authority must show that shippers have an immediate and urgent need for the service contemplated and that existing carriers cannot meet that need.6 And the Commission’s regulations provide that “[rjequests for temporary authority involving service to or from entire States” must be buttressed by need-data relating to “a representative number of points in each such State. . . . ”7 Although Sherman’s temporary authority is now confined to operations within the eight states that either begin or terminate in Wyoming,8 we are still unable to discern how the Commission derived from the materials before it sufficient knowledge to enable an informed exercise of discretion on Sherman’s application.9
*152New if any of Sherman’s supporting statements contain information of the kind required by the Commission’s rules.10 Although these rules are not of a nature binding on the Commission,11 they do denote the contours of what the Commission at least at one time thought it should know. The Commission has not explained why the data called for by the regulations are not necessary in this case; nor does common sense suggest a reason. We do not demand strict compliance with the regulations, but we must insist upon an administrative record that is not “devoid of information” underpinning the application.12
The sparseness of Sherman’s supporting documents, in contrast with the vast area over which temporary operating authority was granted, precludes a holding that the Commission has as yet properly exercised its discretion. There were no statements specifically describing the need for service to or from South Dakota, Idaho and Utah, three of the states for which the application was granted. For Nebraska there was but one statement, and it asserted merely that existing service was inadequate because the carriers furnishing it required up to a month’s notice prior to shipment. Two statements were filed for Colorado — one from a homeowner who based need on frequent moving, and the other from a businessman who had never sought service from existing carriers, and whose only need was for excess moves that his own trucks could not accommodate. The two statements pertaining to North Dakota came from individuals who envisioned a future but uncertain need from possible job transfers, which were not necessarily to Wyoming. They were unhappy with some other carriers, but made no claim that existing service would be inadequate for their purposes.
Similarly, the seven statements relating to Montana all came from mobile home dealers who, for the most part, alleged that their customers are not always able to get service precisely when it is desired. Most of the dealers said that they used their own trucks for most of their transportation activities, and none mentioned any existing carriers from which customers had been unable to obtain prompt service. The few specifies given did not involve any proposed movements to Wyoming. The ten statements dealing with Wyoming all came from parties located in Cheyenne — none of whom specified points in other states to which traffic would be moving, and none indicated pending movements that all existing carriers had refused or were made to handle within a reasonable time.
Thus, most of the statements contained only generalized expressions of discontent with the quality and timeliness of other carriers’ performances. This information might support a grant of permanent authority in the areas where such deficiencies were documented, but it hardly indicates an urgent need for extra service — even for the areas actually discussed in the statements.
While we realize that the Commission must be given great leeway in dealing with applications for temporary authority, we must admonish once again that decisions unsupported by relevant data are simply arbitrary.13 The Commission may be able to explain how the meager evidence furnished it can establish an urgent need for additional service over the eight-state area that cannot be satisfied by certificated car*153riers already operating within the area; but it has not done so, and no rationale for its action is obvious.14 We must, then, remand this case to the Commission for reconsideration of the grant of temporary authority in light of the discussion in this opinion.15
So ordered.
