Photoelectric UBV photometry data (obtained during 1982-1986) are presented for the variable star DR Tau which experienced a novalike brightness increase during 1965-1980. Flares with a duration of several days and highly unusual minima are found in the postmaximum period of stellar activity. The color-brightness relationships are as follows: the greater the brightness, the bluer the B-V color and the redder the U-B color. The observed variability of DR Tau is in agreement with a model describing the activity of young stars (Grinin, 1980) in which it is proposed that the appearance of hot spots in the stellar atmosphere is due to gas accretion.
